Why do you use order of operation?
A standard order of operations lets you know which part of the equation gets calculated first. Without a standard order, someone might calculate 2 + 3 * 4 differently from 4 * 3 + 2, getting 20 in the first case and 14 in the second (by the way, 14 is the correct answer for both by the commonly accepted order of operations).
