-21. 7-7 is 0. 0-7 is -7. -7 -7 is -14 (don't get tricked!) And -14 -7 is -21.
To find the answer to the expression 7-7-7-7-7, you need to follow the order of operations, which states that you should perform any operations inside parentheses first, then perform multiplications and divisions from left to right, and finally perform additions and subtractions from left to right.
In this case, there are no parentheses, multiplications, or divisions, so we only need to perform the subtractions.
Starting from left to right, we have:
7 - 7 = 0
0 - 7 = -7
-7 - 7 = -14
-14 - 7 = -21
Therefore, 7-7-7-7-7 equals -21.
