Negative Numbers

  1. When counting down, after zero, you move into negative numbers. Remember that the rule of which number is bigger is the opposite way around in negative numbers ( for example, -1 is bigger than -2)
  1. When you have to count between negative and positive numbers, the easiest thing to do it draw a number line then count upwards from the negative number to zero, then from zero to the positive number and add together to find the difference.

Example 1:

Let’s say we need to find the difference between -34 and 51. We can draw this on our number line.

negative-numbers-example1

The difference between -34 and 0 is 34 and the difference between 0 and 51 is 51. If we add these together, we get a total of 85. Therefore, the difference between -34 and 51 is 85.

1) -10, -21, 0, 7, 1

Write there number in order of size.
