Can you check my work?
(4+16)- 20+7=
The answer is either 7 or -7?

  • math -

    4 + 16 = 20
    20 + 7 = 27
    27 - 20 = 7

  • math -

    The answer is 7...Always solve the numbers in the brackets first in any given equation. Then the 4+16 in the bracket will cancel out the -20 outside the bracket then you are left with 7!
