__Subtraction

__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
