This worksheet focuses on adding and subtracting numbers in standard form.
In Section A, pupils are asked to fill in gaps, requiring them to adjust numbers so that they remain equivalent as the powers of ten change.
Section B introduces students to adding and subtracting numbers in standard form when the numbers share the same power of ten.
The worksheet then presents two methods for performing these calculations: converting numbers into their ordinary form first or adjusting the numbers to have the same power of ten. Students are required to use both methods to solve problems and then decide on the most efficient or preferred approach.
