Well, let's simplify this expression step by step and have some fun along the way!
First, let's tackle the double negatives: -1 multiplied by -1 gives us 1, and -2 multiplied by -2 gives us 4.
Now we have: (7 - (1 * 1) + (4)
The parentheses indicate what we need to do first, and since there are no more parentheses left, we move on to the next step.
Next, we multiply 1 by 1, which is, well, 1. So, we have: (7 - 1 + 4)
Now, we can do the addition: 7 minus 1 is 6, and when we add 4 to that, we get 10.
Therefore, the simplified expression is 10. But wait, that's not one of the given options! Oh, I guess this expression doesn't fit the choices you provided. So the answer is E. None of the above!
But hey, at least we had fun simplifying it, right?
To simplify the expression (7-(-1*-1)+(-2*-2), we start by simplifying the innermost parentheses first.
-1 * -1 equals 1, so we rewrite the expression as (7-1+( -2*-2)).
Next, we simplify the multiplication in the next set of parentheses.
-2 * -2 equals 4, so the expression becomes (7-1+4).
Now, we add and subtract from left to right.
7-1 equals 6, so the expression becomes (6+4).
Finally, we add 6 and 4 together.
6 + 4 equals 10, so the simplified expression is 10.
Therefore, the answer is not listed in the options provided.
first, the parens are not balanced.
second, I don't see any powers.
third, (-2) to the power -2 is not (-2)(-2). That is (-2)^2
Without some major cleanup, I see no way to get any of the choices.
