Asked by Maia

How do you add, multiply, subtract, divide negative numbers?

Adding and Subtracting: It’s very useful to think of an imaginary numberline, and to keep on mind whether your answer will be getting bigger or smaller. Eg -3 + 5 = 2 (This is because it takes 3 jumps to get to 0, and then another 2 jumps makes 5 jumps in total.) Eg -4 + -6 = -4 - 6 = -10 (the rule is -+ = -) Eg -2 - -8 = -2 + 8 = 6 (the rule is - - = +) Multiplying and Dividing: The same rules apply for multiplying and dividing, except the + and - signs are not next to each other. Eg -6 x 7 = -42 (The answer is negative because we are multiplying a positive and a negative number) Eg -8 x -5 = 40 (The answer is positive because we are multiplying a negative and a negative number. Remember: A positive and a negative makes a negative. A negative and a negative make a positive.
