-3 + 5 * (2 - -6) = 37
It is agreed that brackets should be calculated first and then multiplication should be carried out before addition or subtraction. Therefore:
-3 + 5 * (2 - -6) = -3 + 5 * 8 = -3 + 40 = 37.
It is: (6-3)*(7+4) = 33
Be more specific and add parentheses
(-2)^3 equals -2 times -2 times -2 which equals -8
Incomplete, since there are no operators (plus, minus, times, divides, equals etc) between the terms.

It is: (6-3)*(7+4) = 33
Be more specific and add parentheses
60(x - 15) = 2500 (then simplify the left side of the equation) 60x - 900 = 2500 (then add 900 from both sides of the equation) 60x = 3400 (thn divide both sides by 60 to solve for x) x = 56.66666 (56-2/3)
13 + 7 - (6 + 4) * 2 = 0
Put a parenthesis before the 2 and after the 4.4 (2 x 4.7 - 4.4) = 9.4 - 4.4 = 5 45 divided by 5 times 6 equals 54
(-2)^3 equals -2 times -2 times -2 which equals -8
Incomplete, since there are no operators (plus, minus, times, divides, equals etc) between the terms.

Positive (Plus) times Negative (Minus) always equals a negative (minus).
If you mean: (3+8)-(2*5) then it equals 1
Simple math rules state that a negative times a negative equals a positive!
Negative times positive equals negative.
