Answer:
Here we want to solve the equation:
"2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis."
This can be written as:
2 - 10 + 8 - (-2)
Remember that we can solve this in any order we want, so let's go from left to right:
So we can solve first:
( 2 - 10) + 8 - (-2)
We know that:
2 - 10 = -8
Then we can replace that in the expression to get:
( 2 - 10) + 8 - (-2) = -8 + 8 -(-2)
Now we can solve:
(-8 + 8) - (-2)
We know that:
-8 + 8 = 0
Replacing that in the equation we get:
(-8 + 8) - (-2) = 0 - (-2) = -(-2)
And now we can remember the rule of the signs:
(+)*(+) = (+)
(-)*(-) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
Then:
-(-2) = (-1)*(-2) = +(1)*(2) = 2
The solution of the expression is 2.
