The EE key is for scientific notation which is always a decimal time 10 to some number. Example: 1.23 x 10 to 20th.

When typing the expression - just replace "x10" with the EE key
Type like this:
1.5EE13

You will need to use the exponent button (it looks like this">" except it points up) to do the 18 to the 8th.

### Calculating chemistry 1 scientific equation divided into another?

Use the rules for exponents and you will calculate it by hand
(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3
To enter powers of 10 use the short-cut key [EE]
For example to enter 6.02*10^23 type in 6.02* [EE] 23. When you use the EE key, the base (10) should not appear.

### Dividing 2 different scientic equations into another

Sorry but you are using the word EQUATION incorrectly. All you have is two numbers you want to divide one by the other.
Enter the numerator 1EE (-) 14, press the division key / then enter the 5 EE (-) 12. Press the = sign.
Note: to enter the negative sign in the exponents, use the change sign key marked (-), (+/-) or [+/-] . Do not use the regular MINUS sign.
When you use the EE key, you must not enter the 10. It is understood because EE is a shortcut for *10^.

### I need to find out how to use the powers button. for example 10 to the 23 power. but I don't know where the button is and how to use it.

There's a key marked "EE" (for Enter Exponent) just above the "7" key. This key is used to enter decimal exponents. To enter 1x10^23, press 1 EE 2 3

For exponents to other bases, use the y^x key just above the divide key.
