Order of Operations
Pilot lesson for basic text blocks, numeric answers, and ordering.
Why order matters
An expression can contain several operations. We use a shared order so everyone gets the same result.
Basic order
Parentheses first, then multiplication and division, then addition and subtraction.
Example
Example
Multiply before adding.
5+3\cdot4=5+12=17
Do not always work left to right
Addition does not automatically come before multiplication just because it appears first.
