Order of operations
If you have the expression "3 + 4 x 5", do you add the 3 to the 4 first or multiply the 4 and 5 first? To clear up confusion here, the math world has defined which operation should get priority over others. This is super important. You won't really be able to do any involved math if you don't get this clear. But don't worry, this tutorial has your back.
This example clarifies the purpose of order of operations: to have ONE way to interpret a mathematical statement.
We're throwing everything but the kitchen sink in this one: addition, subtraction, multiplication, and division. Better remember your order of operations, ya hear!
Let's simplify this tricky expression according to the order of operations. Remember: PEMDAS!
Have you heard of PEMDAS? No, it's not some fatal illness. We'll explain here and challenge you with a more complicated example.
Here we have a series of order of operations problems demonstrated in succession so you can really nail down this concept.
Evaluate expressions using your knowledge of order of operations and negative numbers.
