Adding & Subtracting Money

We often need to add or subtract amounts of money with the same unit or different units.

Converting between pounds and pence

Remember there are 100p in £1.
- 200p = £2
- 500p = £5
Mixed amounts of pounds and pence can be written as pence.
- £9 and 30p = 930p
Pence more than 100 can be written as mixed amounts.
- 675p = £6 and 75p

Adding money

Sam has £3 and 60p and Amy has £5 and 80p. They want to find the total.
Add the pounds first:
- £3 + £5 = £8
Then add the pence:
- 60p + 80p =140p
Turn the pence into pounds and pence.
- 140p = £1 and 40p
Find the total.
- £8 + £1 + 40p = £9 and 40p

Subtracting money

Sam has £10 and 50p. He buys a game for £7 and 20p.
Work out what he has left.
- £10 - £7 = £3
- 50p - 20p = 30p
He has £3 and 30p left.

Counting on

Counting on is one way to help you find change.
Sam buys a game for £3 and 99p. He uses a £5 note.
Work out the change he should get back.
- Count up 1p to go from £3 and 99p to £4.
- Count up £1 to go from £4 to £5.
He gets £1 and 1p change.
