Question

Add.

(- 3) + (- 6) + 7 + (- 8) =

Answer 1

\(\Large \color{Black}{\Rightarrow -a + -b = -(a + b) }\)

\(\Large \color{Black}{\Rightarrow a - b = -(b - a) }\)

Two identities.

Answer 2

A negative plus negative is negative.

Answer 3

-10.

Answer 4

-a + -b = -(a+b) and then a-b = -(b-a)
two negatives make it a positive, then you'd have to add

Answer 5

-10

Answer 6

For example if you have \(6 + (-8)\)
Then you'll get
\(6 - 8\)
further

\(\Large \color{Black}{\Rightarrow -(8 - 6) = -2}\)

Answer 7

Or do them step-by-step. Add all the positives first, then the negatives.

Answer 8

That's the easiest way for me
