Key learning points

BIDMAS/BODMAS: brackets, indices, division/multiplication, addition/subtraction.
Place value decides rounding and estimation.
Check answers with inverse operations or rough estimates.

Worked example 1 — Order of operations

Evaluate $4+6\times(5-2)^2$ .

Working

4+6\times3^2=4+6\times9=4+54=58

Brackets and indices before multiplication.

Worked example 2 — Place value

Value of the digit 7 in $37045$ ?

Working

7000

Thousands place.

Worked example 3 — Inverse check

Check $84\div6=14$ using multiplication.

Working

14\times6=84

Multiplication undoes division.
