Question

I am stuck on this. Please help!

Answer 1

the easiest way to solve this is to get rid of all the extra signs!

just remember that a - times a - is equal to a positive, then go from left to right

so starting from left to right, we have

`4 + ( - 2)`
we know that 4 minus 2 is 2, so we know that


`4 + ( - 2) - ( - 2)`
is the same thing as


`2 - ( - 2)`
we also know that two negative signs make a positive sign! so that means that -(-2) is the same thing as +2!

so now we have


`2 + 2`
and we know the answer is 4!

Answer 2

the answer is 4 bc you subtract the 2 and the 2
