Which of these is the largest number?

Negative numbers are shown with a minus sign directly before the number. For instance -10. Negative numbers are used for measuring temperature and also to denote a loss, such as a debt. On negative number lines, the sequence of numbers goes the opposite way to that on positive number lines. For example, in this sequence: -5, -6, -7, -8... etc. You can add/subtract the numbers in any order you like, but don't forget to apply the following rule: for negative numbers move to the left along the number line BUT for positive numbers move to the right along the number line.

It might be helpful if you use your pencil or pen to count along the number line - and above all, remember to go the correct way.

Why are negative numbers would used? An example of how negative numbers are used would be measuring temperatures. If its colder than the freezing point of water (0oC) we say it is a minus temperature. Addition and subtraction can be tricky with negative numbers. One method that might help is to rearrange the problem.
