8-3[25-(7+25)]
i need help evaluating the expression 8-3[25-(7+25)]
8 - 3[25 - (7 + 25)]
Ordinarily, I would say perform the addition inside the parentheses,
but in this problem we are adding 25 then subtracting 25.
8 - 3[-7]
Now, perform the multiplication.
8 - (-21)
Last, the subtraction. Subtracting a negative is adding a positive.
