# Year 3 Subtraction

A question such as 102 – 95 is quite tricky to do on paper, but children should see that it is much easier to do mentally, using addition to work out the answer. By Year 3 they should know all the pairs of numbers that make ten so starting with 95 add 5 to make 100 and then add another 2, to make 102; therefore the answer is 7 (5 + 2).
