Standard Form

Standard form, also known as scientific notation, is a way of conveniently writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.

Standard Form

Examples

3.48 x 104

= 3.48 x 10 x 10 x 10 x 10

= 3.48 x 10000

= 34800

 

3.48 x 10-2

3.48 x 1100

= 3.48 ÷ 100

= 0.0348

 

Finally note that any number raised to the power zero is 1 so:

3.48 x 100

= 3.48 x 1

= 3.48
