Start off with: -4 + (-3) + 6
First of all, when there is a, + sign and a - sign next to each other, the - side wins. E.g. 1 +- 3 = 1 - 3
So, apply this to our one:
-4 -3 +6
From there you solve, you can do this using the number line method or whatever you are into:
=-7 + 6
=-1
The answer is -1
The answer in 3 tenths and 1 hundredths is 0.31
