4 + 3·5 - 64/(4 + 2)3·2
First, do what is inside parentheses first:
= 4 + 3·5 - 64/(6)3·2
= 4 + 3·5 - 64/63·2
Next, do exponents: 64 = 1296 and 63 = 216
= 4 + 3·5 - 1296/216·2
Next, do multiplications and divisions from left to right:
= 4 + 15 - 1296/216·2
= 4 + 15 - 6·2
= 4 + 15 - 12
Finally, do additions and subtractions from left to right:
= 19 - 12
= 7
