Question

I am stuck on this. Please help!

Answer 1

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

Answer 2

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!
