Understand Standard Form on a Calculator

We use the   EXP  or  EE  button on a calculator to enter numbers written in standard index form.

For a negative index, we must use the  +/-  or the  (-)  key before entering the index number.

Example:

To enter 3.67 x 10¹⁴, press the following keys:

3.67

 EXP 

14

To enter 1.29 x 10^-4, press the following keys:

1.29

 EXP 

 +/-   or  (-) 

4

Notice how your calculator displays numbers in standard form.

 1.29   11  or  1.29  E11 

is 1.29 x 10¹¹ not 1.29¹¹

Now let's put your knowledge to the test!
