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.

How do you calculate a discount of 40 10 5 off 62.75 how do I times this in a calculator?
The easiest way is to calculate the price, not the discount. So you would multiply the price times 60% (100% - 40%). Then multiply that result times 90% (100% - 10%). Then multiply that second result by 95% (100% - 5%). The formula, using P as price, looks like this: ((P*.6) * .9) * .95 Because all the operations are multiplication, you can remove the parantheses and multiply in any sequence. So the following formula is equivalent: P (.6*.9*.95) or P * .513 So your price = 62.75 * .513 = 32.19 [which means the discount is 30.56 (62.75 - 32.19) which is the same as P * (1 - .513)]

2nd [CATALOG], solve( , enter equation, variable and guess after the bracket, close brackets with " ) ". You can also put lower and upper bounds after the guess.
Springs exhibit a physical property known as elasticity. This property allows it to be pushed and pulled easily despite often being made of rather tough materials, because minimal amounts of the material in the spring are actually being pulled and pushed on, but the whole is still moving drastically.
Who was the inventor of a mechanical calculator for adding number?
You may be referring to the Curta, the small, hand-cranked mechanical calculator
introduced by Curt Herzstark in 1948. It can be used to perform addition, subtraction,
multiplication, division, square roots and other operations. It was considered the most
accurate calculator until the introduction of the electronic ones in the early 1970s.
14 year olds should not use adult BMI charts as they are still growing. Your doctor knows you best and if you are healthy you are probably all right. Have you just had a growth spurt and are waiting for your weight to catch up? Are you a fidgety person, never still, always on the go? that will increase your metabolic rate and keep your weight down. In a country where the citizens are rapidly becoming obese with all the attendant health problems I wouldn't worry about being a little underweight, just eat a healthy diet, exercise and be thankful you don't have to watch the calories.
Excel certainly helps...you'll find a number of options, including several for calculating payments using "formulas" (the Fx features) that may get you there...even an amortization one. So presuming you know interest rate, principal and time variables (like payment at start or end of period, how long a term, etc) - and - this is even more important - they are defined the same by the lender simularly to how the function thinks - you can calculate it and should really be pretty close. Pen and paper would rely on reference tables/charts for giving a payment amount per 100 (or thousand) dollars at a number of rates (hopefully one is the right one) and over specified terms. Available at most any lender, charts are common in most newspapers for at least the ranges they are dealing with commonly. Of course any unusual aspect to the loan your calculating....variable rates, fixed payments, early payoffs, etc., complicates it more so.

How do i reset the Ti-84 password?
Memory Method
1. Go to 2nd [MEM].
2. Press 2 (or scroll down to Mem Mgmt/Del).
3. Press ALPHA B or scroll down to AppVars.
4. Go to the Application Variable named MirageOS.
5. Delete it by pressing DEL.
6. If it asks for a confirmation, go to yes and press ENTER.
7. Go to the App MirageOS.
8. You can now enter without a password.
Self test method
This method works when you have the memory access blocked.
1. Press mode.
2. Press [alpha] + "s".
3. Press ok to begin the self test.
4. This will erase the RAM memory, and you will be able to get in the program.
5. If it does not erase the password, it will unblock the memory access, then you can delete the appvar where the password is stored.
Battery Method
1. Take out the batteries and put them back in (when the calculator is turned off). This should clear the RAM memory.
2. After the memory is cleared, you can go into the calculator password free.
The last known AUTHENTIC 1783 Nova Constellation Pattern 1000 Mark coin sold at the Garrett sale in 1979 for $190,000 -- I would estimate that coin would probably be worth more than double that today. HOWEVER, there are MANY electrotype replicas in existance. They will look like the original, but a trained eye can tell the difference. These are worth a couple dollars. If you believe your coin is genuine, I suggest you check out the ANACS website to see if they will be attending any upcoming coin shows in your area, where you can get a free professional first-hand appraisal : http://www.anacs.com
