A recurring decimal is one that has an infinite number of digits after the decimal point.

An irrational number is one that cannot be written in the form a/b where a and b are integers and b is not equal to 0.

A terminating decimal is one that has a finite number of digits after the decimal point.

Maths

In this unit, pupils formalised their understanding of the index laws. This understanding will allow them to perform calculations with values written in standard form more efficiently.

The conditions for standard form mean that pupils have explored how different powers of 10 can be written in the prior unit. In this unit, this understanding is generalised and the index laws formalised.
