There are 225 sweets in a jar.
Jack takes 35 sweets out of the jar.
Jane takes 15 less than Jack out of the jar.
How many sweets are left in the jar?
First we work out how many sweets Jane takes.
This is 15 less than Jack.
35 - 15 = 20
So Jane takes 20 sweets.
Sweets left in jar = 225 - 35 - 20 = 190 - 20 = 170 sweets
