Here we have provided some questions on adding and subtracting measurements in millimetres and centimetres. Learners will need to provide their answers in the required unit of measurement.

Section A gives sums between measurements in millilmetres with an answer required in centimetres and millimetres.

Section B then gives sums of measurements in cm and mm and requires the answer in mm.

Sections C and D involve subtractions of a mixture of measurement units.

Section E provides two addition pyramids with gaps to fill.
