Order of operations (not algebra)
2^3 - 8[4-(-3 + 16) + 4
8 - 8(4 - 13) + 4
8 - 8(-9) + 4
8 - -72 + 4
8+72 + 4
84
2^3 - 8[4-(-3 + 16) + 4
8 - 8(4 - 13) + 4
8 - 8(-9) + 4
8 - -72 + 4
8+72 + 4

2^3 - 8[4 - (-3 + 16) + 4]
= 8 - 8[4 - 13 + 4]
= 8 - 8[-9 + 4]
= 8 - 8[-5]
= 8 - [-40]
= 8 + 40
= 48
= 8 - 8[4 - 13 + 4]
= 8 - 8[-9 + 4]
= 8 - 8[-5]
= 8 - [-40]
= 8 + 40
= 48
