CASIO fx-115ES I need to calculate and fnd a modulus remainder.I need to divide the number 352 by the number 91 and find the remainder. I need to use the modulus operator. Can this calculator perform...

Actually, the answer is 79.

The fx-115ES does not have a key for the modulus operation. Nor does it have an integer-part or fractional-part operation. However, it is possible to calculate the remainder using integer arithmetic.

Press MODE 4 to shift into integer mode. Then type in 3 5 2 - 9 1 * ( 3 5 2 / 9 1 ) = and see the answer 79. It's a pain as both numbers have to be entered twice, but it does get the job done.

To get back to working with real numbers again, press MODE 1 ( or MODE 2 for complex).

360 degrees divided by 29 spaces

What do you really want to do? 360/29 gives 12.4137931 degrees. Is it not 360 divided by 30? That looks more common, and the result is 12 degrees. That is what you get if you want to inscribe a regular 30-gon in a circle.

How do i change L to mL on the casio fx-115es

The scientific prefixes are
  1. Giga = 1 billion ( times 1 000 000 000)
  2. Mega = 1 million (times 1 000 000)
  3. Kilo = 1 thousand (times 1000)
  4. deca = 10 (times 10)
  5. deci = one tenth ( divided by 10) or multiply by 0.1
  6. centi = one hyndredth (divide by 100) or multiply by 0.01.
  7. milli = one thousandth (divide by 1000) or multiply by 0.001
  8. micro = one millionth (divide by 1 000 000) or multiply by 0.000 001
  9. nano = one billionth (divide by 1 000 000 000) or multiply by 0.000 000 001
So 1 milliliter = 1mL = 1L/1000 = 0.001 L
1L = 1000 mL
It is instructive to learn the meaning of these prefixes, because they always mean the same thing, regardless of the units you are dealing with.
Ex: The population of the Earth is about 6 Gigapersons (It does not exists, but it illustrates the principle. I hope you win a jackpot of 10 megadollars. (M$)

Hope it helps.

Problems with fractions on the Casio fx-115es

To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.
Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

Hope it helps.
