Subtraction of measures


Subtraction without Regrouping

EXAMPLE

Subtract 18 m 24 cm from 48 m 36 cm


Step 1: Subtract centimetre column

(36−24) = 12cm

Step 2: Subtract metre column

48−18 = 30m


Subtraction with Regrouping

EXAMPLE

Subtract 73m 44cm – 54m 75cm


75cm cannot be subtracted from 44cm. So take 1m from 73 m and then add with 44 we get 100 + 44 = 144cm.

Step 1: 144cm −75cm = 69cm

Step 2: 72cm −54cm = 18cm
