Remember that there are 100 p in a pound.
So if we add 1 p and £1 we get £1.01
Add 253 p to £10.
Working in pounds, we must work out £10.00 + £2.53
Remember when we add in money, we use decimals and must consider the place values for pounds and pence.
The answer must be written with a £ sign, so the answer is £12.53
