'Understand Standard Form on a Calculator' worksheet

Key stage:  KS 3

Curriculum topic:   Number

Curriculum subtopic:   Use Calculators/Technology for Accuracy

Difficulty level:  

Worksheet Overview

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!
