This equation simplifies to:
3 + 5−4-4−4 + 3 = -203 - 20 + 3 = -20-17 + 3 = -20-14 = -20
Therefore, the equation 3 + 5−4-4−4 + 3 does not equal -20.
This equation simplifies to:
3 + 5−4-4−4 + 3 = -20
3 - 20 + 3 = -20
-17 + 3 = -20
-14 = -20
Therefore, the equation 3 + 5−4-4−4 + 3 does not equal -20.
