Multiplication/Division and Addition/Subtraction are what comes first from left to right.

So if you have:

6 / 2 * 3

You would divide first, because it comes first before multiplication.

Same goes for Addition & Subtraction.

6 - 3 + 5

You subtract first, since it comes first from left to right.
