Adding, Subtracting and Multiplying measurements is just the same as all numbers.
Adding, Subtracting and Multiplying measurements is just the same as all numbers.
You just have to be careful to notice the units. Are they the same or do you need to change them to the same unit first?

Calculate the answers to the measurements below:
Notice the units: Is it cm? m? mm? g? kg? mins? hours?
Add the following:
(i) 12 cm + 15 cm + 13 cm =
(ii) 12 m + 17 m + 4 m =
(iii) 28 cm + 16 cm + 6 cm =
(iv) 10 cm + 3 cm + 9 cm =
(v) 5 mm + 19 mm + 4 mm =
Extra for Experts
(vi) 13cm + 15mm = ______ mm
(vii) 3kg + 500g = _____ kg
(viii) 43 mins + 2 hrs = _____mins
Subtract the following:
(i) 13 g - 6 g =
(ii) 16 kg - 2 kg =
(iii) 13 minutes - 8 minutes =
(iv) 12L - 8L =
(v) 20g - 8g - 4g =
Extra for Experts
(vi) 28cm - 80mm = ______ mm
(vii) 450g - 280 g = ______ g
(viii) 3 hrs - 70 mins = _____mins
Multiply the following:
(i) 5 mins x 3 =
(ii) 10 kg x 6 =
(iii) 3 hours x 4 =
(iv) 5 g x 4 =
(v) 2 x 12cm =
Extra for Experts
(vi) 12cm x 10 = ______ m
(vii) 50g x 8 = ______ g
(viii) 40 mins x 3 = _____ hours
What is the answer? Don't forget to say what unit it is.
