Question

Find the value of each:Part a4 -6 + 15 + 15 =Part b50-42+10=

Answer 1

For this case we have the following expression given:

`4-6+15+15`

If we operate the first two terms we got:

`-2+15+15=-2+30`

And then we can add the final two terms and we got:

`-2+30=28`

For the second part we have:

`50-42+10=8+10=18`
