Question

Match each expression on the left to its equivalent value on the right. Some answer options on the right will not be used.

Answer 1

Let us write out our expressions:

`\begin{gathered} -29+(-7) \\ -34+(-94) \\ -8+(-14) \\ -12+(-48) \end{gathered}`

The trick here is to get rid of the minus, then solve the sum as usual, and add a minus to the result. Let us do that for each of them:

-29+(-7)] Step one gives us:

`29+7`

Step two gives us:

`36`

Step three gives us:

`-36`

Then, -29+(-7) should be linked to -36.

-34+(-94)] Step one gives us:

`34+94`

Step two gives us:

`128`

Step three gives us:

`-128`

Thus, -34+(-94) should be linked to -128.

-8+(-14)] Step one gives us:

`8+14`

Step two gives us:

`22`

And step three gives us:

`-22`

This implies that -2+(-14) should be linked to -22.

-12+(-48)] Step one gives us:

`12+48`

Step two gives us:

`60`

And step three gives us:

`-60`

Then, -12+(-48) should be linked to -60.
