Calculators

Oh, dude, getting rid of that pesky little "K" on your Texas Instruments calculator is a total breeze. All you gotta do is switch your calculator from scientific notation to standard notation. Just hit the "MODE" button, navigate to the "FLOAT" option, and voila, that annoying "K" will disappear faster than my motivation to go to the gym. Easy peasy, like taking candy from a baby.

To find the inverse of a matrix on a Casio fx-991MS scientific calculator, you first need to input the matrix you want to find the inverse of. Then, press the "SHIFT" button followed by the "MODE" button to access the matrix mode. Select the matrix you want to invert by pressing the corresponding number key. Next, press the "SHIFT" button followed by the "MATRIX" button, and then press the "x^-1" button to calculate the inverse of the matrix.

The "shell oil trick" on a calculator is a method used to quickly clear all variables and functions stored in the calculator's memory. This can be helpful when starting a new calculation or if you want to ensure there are no residual values impacting your current computation. To perform this trick, you typically press a combination of buttons, such as "2nd" + "MEM" + "7" + "1" on a TI-84 calculator. It essentially resets the calculator to its default state.

The TI-83 does not have the cot button, however, if you type 1/tan( then this will work the same as the cot since cot=1/tan.

The other way to do this is to type (cos(x))/(sin(x)) where x is the angle you're looking for. This works because cot=cos/sin

Ah, the MRC button on a calculator is a handy little tool. It stands for Memory Recall, which means it brings back whatever number you stored in the calculator's memory. Simply press the MRC button after you've stored a number, and it will display that number for you to use in your calculations. Just like adding a happy little tree to your painting, the MRC button can add a touch of simplicity and convenience to your math equations.

Ah, the GT key on a calculator stands for "greater than." It helps you compare two numbers and see which one is larger. Just remember, math is like painting a beautiful landscape - every key on the calculator has its own special purpose to help you create something wonderful.

To find the determinant of a matrix on a Casio fx-991MS calculator, you first need to enter the matrix into the calculator using the matrix mode. Then, navigate to the matrix menu and select the matrix you want to find the determinant of. Finally, choose the option to calculate the determinant, and the calculator will display the result. Remember that the determinant of a matrix is a scalar value that represents certain properties of the matrix.

The little M says there is something stored in the calculator's memory.

If you don't plan on using the memory, forget about it; it's not a problem,
and it won't interfere with anything you'll need to do.

If you want to use the memory, or just want to get rid of the little M, then CLEAR THE MEMORY.

You can hit ' MR ', (memory recall), which shows what number is in the memory.
Then use ' M- ' to subtract that number from the memory.
That leaves zero in the memory.

A scientific calculator typically has around 45 to 50 buttons, including numerical keys, mathematical function keys (such as addition, subtraction, multiplication, division), memory keys, trigonometric function keys, logarithmic function keys, and more. The exact number of buttons may vary slightly depending on the specific model and brand of the calculator.

Oh, dude, you just press 0.7734 on the calculator and then turn it upside down. It spells out "hello." It's like calculator magic or something. So, yeah, that's how you type "hello" on a calculator.

How is the present day calculator different from the pascalline give any two example

Well, honey, first you open that darn paper roll cover on the back of the CASIO DR T120. Then you pop that thermal paper roll in with the shiny side facing down. Finally, you close the cover and feed the paper through the slot, making sure it's nice and snug. Voila! You're ready to crunch those numbers like a boss.

Sure, if you try to divide by zero on a calculator, it will probably throw a fit and give you an error message. So technically, attempting to perform an impossible calculation like that could "break" a calculator in terms of its normal functioning. But hey, at least you'll have a good story to tell about how you defeated a calculator!

I just successfully completed the task of loading paper into the canon palm printer p1-dh v. My problem was that the paper was not being grabbed by the "Feed" button. Where I was guiding the paper, after feeding the paper through the back of the machine (the slot is located on the outside of the back of the machine), the paper naturally wanted to enter underneath the black plastic plate where it would end up underneath the entire printing mechanism. As the instructions indicate, the paper does not actually feed "under the black plastic plate", it should feed through it. There are two rectangular silver tabs, one on each side of the proper paper entry slot. I cut the paper at a very slight angle (edit:actually, if you cut it into a truncated triangle, it's even easier!) and finally found the magic entry point. Because the machine is so tiny, that entry slot is almost invisible, except for those two silver tabs. After you manage to insert the end of the angled cut through the "invisible slot" be sure the entire edge of the paper actually enters the slot so that when you push the "Feed" button, the paper is grabbed and fished through evenly. (edit: If the paper cannot be advanced by the "Feed" button, remove the plastic cover by pushing it toward the direction of the arrows on the left side which are embossed directly on the clear plastic cover and pull the paper manually. When reinstalling the cover put the front end in first, make sure the entire cover is flat to the printer case, then push the front slightly toward the back and finally slide the cover forward until it is seated). Hope this helps somebody! (edit: It sure did!) I found that folding the end of the paper into an arrow and then watching the feed button rotate, I could then easily see where the paper should be inserted. With it folded like that, it went in like a hot knife in butter.

Your answer did the trick for me! I have also found it easier to store the paper inside the machine, using the arm only when printouts get really long, just to prevent accidentally entering the back slot. Works much better than having the roll fall off and unravel.

I found a washer about an inch in diameter with the hole in the middle just large (or small) enough to fit over the paper arm. It holds the roll on and since it has to be tilted to fit on the arm it wont fall off while handling the printer. BTW...your solution kept me from trashing this great little printing calculator.

• scientific notation, 1.5 * 10^8
• fixed point notation, 150,000,000

Processor. It is sometimes called "Central Processing Unit" or CPU.

well i wouldn't know since in only yrs old but i have read the history of calculators and only found a ALGEBRA calculator that shows work I'm still looking for a calculator that shows work......my teacher says there shouldn't be one because if there is kids will just use them for their homework and show their work just use that calculator........sooo.....yeah....bye-bye pplz

Ah, accessing games on your TI-84 Plus Silver Edition is a wonderful adventure! First, you'll need to download the games onto your computer and then transfer them to your calculator using a USB cable. Remember to follow the instructions carefully and soon you'll be enjoying a world of fun and creativity right at your fingertips. Just remember, there are so many possibilities waiting for you to explore!

The very simplest calculator will have:

On/Off button

The ten digits 0-9

The four simple functions + - / x

Probably an '='

Thus minimum is 16, probably arranged in 4 rows of 4 buttons.

Well, isn't that a happy little question! The raw materials in a calculator include things like plastic for the casing, metal for the circuitry, silicon for the semiconductors, and of course some electronic components like wires and batteries. Just imagine all those materials coming together like a beautiful painting to help us crunch numbers and create wonderful things.

1. Accuracy

Graphing by hand is prone to errors, especially when working with equations that have fractional or decimal values. When graphing by hand, it can be difficult to plot points accurately, and small mistakes can lead to incorrect solutions. A graphing calculator, on the other hand, provides precise and accurate plots, minimizing the risk of errors and ensuring that the system of equations is solved correctly.

2. Speed

Graphing by hand can be time-consuming, especially if the equations involve fractions, decimals, or complex expressions. A graphing calculator can quickly plot the lines and identify the point of intersection, which represents the solution to the system. This saves significant time compared to manually plotting each point, drawing the lines, and finding where they intersect.

3. Handling Complex Systems

Some linear systems may involve equations with more complex coefficients, decimals, or large numbers. Solving these by hand can become tedious and challenging, especially if the equations have fractional values or large integers. The graphing calculator can handle these computations effortlessly and plot the solution without the need for manual calculations.

4. Multiple Equations

For systems of equations with more than two variables, graphing by hand can be nearly impossible in a two-dimensional space. While graphing two lines to find their intersection is simple, graphing three or more planes (in a 3D space) requires different tools. A graphing calculator, however, can work with multiple equations and variables, solving the system more easily and without needing a physical 3D plot.

5. Visual Clarity

Graphing by hand requires careful and precise plotting of points and lines, which can sometimes make the solution unclear or difficult to visualize, especially if the lines are close together or intersect at non-integer values. A graphing calculator provides a clear and detailed visual representation of the system, where you can quickly observe the intersection and determine the solution.

6. Efficiency with Multiple Solutions

In some cases, linear systems may have no solution (parallel lines) or infinitely many solutions (the same line), which can be difficult to identify by hand, especially if the lines are close. A graphing calculator can quickly show if the lines are parallel (no solution) or if they overlap (infinite solutions), helping you identify the type of solution without additional steps.

7. Learning Tool

For students, a graphing calculator can serve as a valuable learning tool. It allows them to focus on understanding the concept of linear systems and how to interpret their graphical representation, rather than getting bogged down in the manual process of graphing and calculation. It also allows students to experiment with different equations and see the immediate effects of changes to the system.

8. Convenience and Ease of Use

Once you input the equations into the graphing calculator, it performs all the necessary calculations and produces the graph with minimal input. This convenience makes it ideal for checking answers quickly or solving more complicated systems that would take longer to graph by hand.

In Summary:

A graphing calculator allows you to solve linear systems more accurately, quickly, and with greater ease compared to graphing by hand. It removes the potential for human error, saves time, and handles more complex systems of equations effortlessly. It also provides clear and immediate visual feedback, making it an ideal tool for students or anyone looking for a more efficient way to solve linear systems.

On most calculators, the exponent button is denoted by a caret symbol (^) or a raised "x" symbol. To calculate an exponent, you typically input the base number, press the exponent button, and then enter the exponent value. For example, to calculate 2 raised to the power of 3, you would input "2 ^ 3" or "2 raised to the power of 3" on the calculator.

Hello, I had the exact same problem. What you want to do is reset the calculator, (if you don’t know how you can just search it up with your model online). It should come up with three options. You want to select the one which says Setup Data. Then just press OK, and it should be back to normal. I am not sure if this changes anything else, but using it so far it doesn’t appear to do so. I hope this helped.

Afaik it can do summation only in statistic- and regression operation-mode, where you put in x, or, x y sample data from 0 to n samples. There it is possible to create a modified summation formula on these data variables.
