Question

Find the of 6+ -4 using the number below and use arrows to represent the integers Does the -4 + 6 give the same sum as 6 -4? Use the number line below

Answer 1

Given 2 number lines and two expression

`\begin{gathered} \exp ression,1=6-4 \\ \exp ression,2=-4+6 \end{gathered}`

To Determine: If expression 1 and 2 are the same

Using number line to solve expression 1 as shown below:

From the above, it can be seen that 6 - 4 means moving from 6 to the left 4 time spaces, which give us 2.

Therefore, 6-4 = 2

Using number line to solve expression 2 as shown below:
