Question

Mandy is trying to subtract 4 - 12, and she has asked you for help. How would you explain the process of solving the problem to Mandy, using a number line?

Answer 1

To solve 4-12 on a number line you would need to start on 4 then move 12 places to the left since 12 is negative. Twelve would be negative because you cant take away 12 from 4 . When you move 12 places to the left you would get -8

Answer 2

representing the number 4 - 12 in the number line

A number line is a line in which all the positive and negative numbers are marked on it.

the number line is represented in the diagram attached below.

when 4 is subtracted by 12 then we move left on the line graph and the point -8 will be represented in the graph.
