They're both wrong - the answer is 12.
The commutative property + Order of operations + disambiguation results in
6 + 6 + (6 x 6 x 0)
PS C:\WINDOWS\system32> 6 + 6 + 6 * 6 * 0
12
Python, C++, Java, C# - all yield the same result.
you could sort-of ignore OOO if the equation were re-written and evaluated left to right as
6 * 6 * 0 + 6 + 6
Without understanding the commutative property, you would end up with 2 different and "correct" answers.
But the commutative declares that 6 + 6 + 6 * 6 * 0 = 6 * 6 * 0 + 6 + 6. If we didn't have that property, computer programming would not work because math wouldn't work.
