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 math problems and make them easier, such as counting in steps, rounding numbers up or down, or using number bonds.
