more information
You may notice that BEDMAS, in certain occasions, is substituted by PEMDAS:
P - Parenthesis
E - Exponents
M D - Multiplication and/or Division
A - Addition
S - Subtraction
The fact that either BEDMAS or PEMDAS is used is an iindication of a very important thing to note:
Multiplication and Division are AT THE SAME LEVEL! That is, EITHER ONE CAN BE PERFORMED FIRST.
Here is a more in-depth explanation of the order of operation for integers, with some examples worked out. If you understand how to manipulate the order of operation with integers, you are set! That's because it is applied the same way for decimals and fractions.
