I need to find the reciprocal button the FX-115MS

It seems that this calculator doesen't have Financial capabilities!

Press SHIFT MODE 1 to put the calculator into MathIO mode.

The lack of a mod function makes this more than a bit painful. Here's one way:

Press MODE 4 to go into BASE-N (integer) mode. If the display doesn't read "Dec", press the x^2 key. Now calculate 4587-4587/8*8 (press 4 5 8 7 - 4 5 8 7 / 8 * 8 =, where * is the multiply and / is the divide).

You can calculate other mod problems the same way. a mod b is a-a/b*b.

Press MODE 1 to return to your previously scheduled calculations.

To calculate modulo with the FX-115MS calculator, follow these steps (in BASE-N DEC):e.g.: 9%4=19 (minus) 9 (divide) 4 (times) 4 =so, 9-9/4*4 will yield the correct answer of 1

can you tell me the answer to this question

round 618 to two decimal places

Hello,
Here are some exemples

there is one button ab/c beneath CALC... if u want to calculate 7 mod 4 then... u should press 7 then ab/c 4 and equal to
1, 3 ,4 which is 4*1=4 and 7-4=3 remainder...

There must be [ ^ ] or [ y^x ] button it's the function of the power so use it like this: x power y
Rate me, thanks.

Hello
Use the general power key labelled as [^], or [X to the y] or [Y to the x] depending on calculator.
3500000 [ / ] [(]7.5 [^] 20[)] [=] gives 1.103678993 E -11
Hope it helps.
