By pressing the three digits that make up the number 100.
1 and 0 and the power button (10 squared or to the power 2)=100 :P
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.
0.47. check it out for yourself. this in a fraction is 47/100. get a calculator and divide 47 by 100.
It changes the sign of your answer between positive and negative. For example, if your calculator says 50 and you press the +/- button, it will change to -50. Press it again and it changes back to 50. It is useful if you need to multiply several numbers together and then subtract them from another number. For example say you multiplied some numbers on your calculator and got 52.932646 and you need to subtract that from 100. Instead of clearing the calculator and typing 100 - 52.932646, you could just press the +/- button to get -52.932646 and then add 100, and you will get the correct answer. It saves a step.

On a scientific calculator, you could press 1, and then press antilog (base 10) twice. The key might be labelled something like 10x.
No need for a calculator. 10% of 100 is equal to (0.1)(100) = 10. If you wanted to use a calculator, just multiply 0.1 times 100.
A markup calculator is used to work out the final retail cost of an item if you know the price it was bought for and the percentage markup (how much profit) you want to make. There are online calculators which can do this automatically for you, or you can just use a normal calculator: for example, if you buy something for 100 and want to make 20% profit, the final price should be 100*1.2 = 120.
On average a calculator weighs about 100 grams.
To convert 30% to a decimal divide by 100: 30% ÷ 100 = 0.3 (enter 0.3 on the calculator).
Hit keys in the following sequence:[4] [÷] [25] [=] (the display shows 0.16) [x] [100] [=] (the display shows 16)That will carry out the calculation ...( 4 / 25 ) = 0.16(0.16 x 100) = 16 percent
(1 + 100) * 50
use a calculator ;-)
i bought a scientific calculator for about 90-100 dollars while it was on sale
Example: 1 / 4 x 100 = 25 on a calculator so a quarter is 25 per cent where / is the ÷ symbol on a calculator.
