Let us write out our expressions:

[tex]\begin{gathered} -29+(-7) \\ -34+(-94) \\ -8+(-14) \\ -12+(-48) \end{gathered}[/tex]

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:

[tex]29+7[/tex]

Step two gives us:

[tex]36[/tex]

Step three gives us:

[tex]-36[/tex]

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

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

[tex]34+94[/tex]

Step two gives us:

[tex]128[/tex]

Step three gives us:

[tex]-128[/tex]

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

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

[tex]8+14[/tex]

Step two gives us:

[tex]22[/tex]

And step three gives us:

[tex]-22[/tex]

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

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

[tex]12+48[/tex]

Step two gives us:

[tex]60[/tex]

And step three gives us:

[tex]-60[/tex]

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