2207
Substitute the numbers into the equation: -4 (-4 - 10 x 8 x 7) -7^2
Use BIDMAS (Brackets, Indices, Division, Multiplication, Addition, Subtraction) to find out the order in which to do the equation. Do the brackets first: - 10 x 8 x 7 = 560
-4 - 560 = -564
Then, add that back into the equation: -4 (-564) - 7^2.
-4 x -564 = 2256
7^2 = 49
2256 - 49 = 2207
