Pounds and pence
Money comes in pounds and pence. One pound is the same as 100 pence.
Pounds are written with a £ before the number:
- for example two pounds is written as £2.
Pence are written with a p after the number:
- for example twenty pence is written as 20p
Sometimes pounds and pence are written together as £ then the number of pounds then a dot then the number of pence.
- for example one pound and fifty pence is written as £1.50
How do you add and subtract money?
If you are just working with pounds, or just working with pence, you can add and subtract just like with ordinary numbers.
If you are working with pounds and pence, remember that 100±è=£1
Bridging through 100 can help. Here's what to do:
work out what you need to add to your first number of pence to make 100
add 1 to the pounds for the 100 pence
subtract what you added from the second number
the number you have left says how many pence you have
add this to the number of pounds you have for the final answer
Example
What is 70p + 40p?
What do you need to add to 70p to make 100p?
70p + 30p = 100p
This makes £1.
Take 30p away from 40p
40p - 30p = 10p
Add this to the pounds to make £1.10±è
