Calculators
A calculator is a hand-held inexpensive electronic device used to perform the operations of arithmetic. The simplest calculators can only do addition, subtraction, multiplication, and division, while scientific calculators can handle exponential operations, and trigonometric and logarithmic functions.

Calculator hp How much will 600.00 per month for 30 yrs.at 4.5 percent can you borrow?
Let "q" be your monthly payment (600), N be the time length of the loan in MONTHS (360) and "i" be your monthly interest rate. This last number is a little tricky and depends on exactly what is meant by 4.5% interest. I assumed they charged interest every month on your balance so after a year it was 4.5% . Then i = .00367. The formula is then: P = (q/i)[((1+i)^N) - 1]/(1+i)^N = (600/.00367)[((1.00367)^360) - 1]/(1.00367)^360 = 163488[3.7389 - 1]/3.7389 = $119,762 the amount you can borrow.
What is the difference between a calculator and a pencil?
A calculator, at least the modern ones, are devices that will "crunch numbers" and find answers to mathematical processes we instruct them to undertake. They have programs that they run to perform mathematical operations on command (but according to their limits). A pencil is a writing device that we must power up with our body and our mind.
How do I calculate the square root of 32 divided by 2 without the use of a calculator?
sqrt(32)=sqrt(16 x 2) = sqrt(16) sqrt(2) = 4 sqrt(2)
Dividing 4 sqrt(2) by 2 , you get 2 sqrt(2) . This is the answer.
Well the modern calculator with circuits was invented by William Seward Burroughs, while the first calculator (slide and rule) was invented by W. Oughtred (1574-1660).
Nobody "discovered" the calculator in the contemporary sense. It was a natural outgrowth of continuous integrated circuit miniaturization.
What are the materials used to make a calculator today?
Made of plastic, wires, buttons, a computer, and a screen
Will a solar powered calculator work in a dark room?
No, because the calculator is solared power so which means that the calculator will only work in a room that has light or it can also work outside during the day when the sun is out
What is the change of sign key on a calculator?
The change of sign key converts the value from positive to negative or vice versa.
For example, if the number shown in the calculator is 100, clicking the button will convert it to -100. Clicking it again will convert it back to 100.
Where is the percentage sign on a graphing calculator?
You can't access a percentage symbol on the calculator.
The easiest way to use percents is to simply divide the number by 100. If you insist on using something like a percent symbol, you'll have to use the sub( command in the [2nd][0](Catalog) menu. Supplying sub( with only one argument, i.e. sub(43) will divide the input by 100 automatically.
Calculators are used to solve maths problems quickly and reliably
How does the love calculator work?
Love calculators are novice online calculators to determine how much two people love each other. The percentage is worked out by using a simple math method.
How do you find the square root of a variable?
The square root method:
If u is an algebraic expression and d is a positive real number, then u^2 = d has exactly two solutions:
If u^2 = d, then u = √d or u = - √d
Equivalently,
If u^2 = d, then u = ±√d
To quickly calculate math problems that would (based on opinion) take too long to do by hand. It's very useful when you're doing algebra. It's just a modern convenience. :)
Does 0.9 it mean 0.9 pence or 90 pence on the calculator?
If you are dealing with Pounds and Pence, 0.9 would indicate 90 Pence. 9 Pence would be shown as 0.09 on your calculator.
How do you write on a scientific calculator?
You can type letters from A-F, X, Y and M by pressing alpha.
What was the first calculator invented called?
If you mean electronically, then it would still be called a calculator. But, before that, people used the abacus, which had lots of sliding thingies and such.
How do you use square roots on your TI-30X IIS calculator?
Well i had the same qustion first u press 2nd then you press the button that looks like this ^ then put your number inexample: 3 2nd ^ 78 it would be 4.272658682
Is their Mercury in math calculators?
Mercury is a heavy metal that is very toxic and is a liquid at room temperature. For this reason I do not believe that there would be any mercury in calculators. I do not know why mercury would be used in manufacturing. I don't believe is is commonly used in computer chips. Whether or not mercury is actually used in calculators or in manufacturing of calculators depends varies by manufacturer.
When were calculators first mass produced?
the first mass produced calculator is the arithmometer developed by Charles xavier thomas de colmar in 1820 in France. this device performed the same type of computations with leibniz's stepped reckoner but was more reliable
