The first operation is
[tex]-14+(-42)[/tex]
First, we have to get rid of the parenthesis, to do that, we just multiply signs to get
[tex]-14-42[/tex]
Now, we sum these numbers since they have the same signs
[tex]-14-42=-56[/tex]
Therefore, the answer to (a) is -56.
The second operation is
[tex]34+(-24)[/tex]
We get rid of the parenthesis
[tex]34-24[/tex]
Then, we subtract these numbers since they have different signs
[tex]34-24=10[/tex]
Therefore, the answer to (b) is 10.
The third operation is
[tex]-7+10[/tex]
We just subtract these numbers since they have different signs
[tex]-7+10=3[/tex]
Therefore, the answer to (c) is 3.
The fourth operation is
[tex]-50+45[/tex]
We just subtract
[tex]-50+45=-5[/tex]
Therefore, the answer to (d) is -5.
The last operation is
[tex]8+88[/tex]
We just sum
[tex]8+88=96[/tex]
Therefore, the answer to (e) is 96.
