# Addition and Subtraction (Year 5)

In Year 5, the third year in KS2, children will be exposed to even more difficult addition and subtraction problems in Maths, such as decimals. They should by now be familiar with the best methods to use to work out the answers to problems requiring them to use the plus or minus symbols.

Addition problems use the plus sign + (for adding) and subtraction problems use the minus sign - (for taking away) when they are written down. The plus sign denotes that one or more numbers should be added to others to get a larger amount, for example 5 + 5 = 10. The minus sign means that one or more numbers should be taken away, for example 8 - 4 = 4. There are several techniques that we can use to simplify maths problems and make them easier, such as counting in steps, rounding numbers up or down, or using number bonds.
