BASIC OPERATIONS
Adding, Subtracting, Multiplying, Dividing are the basicoperations in mathematics
When an expression has more than one of these operationtogether, we need to process them in proper order
When adding or subtracting, either operation can be donefirst (Rule: Always go from “Left” to “Right”)
Likewise, when multiplying or dividing, either operationcan be done first, always go from “Left” to “Right”

When adding, subtracting, multiplying, and dividing areall in one expressions, we must multiply or divide first.Adding or subtracting will be done afterwards

(PARENTHESIS)
Parenthesis are “brackets” in an equation
All expressions inside a bracket should be simplifiedbefore any operation outside of the brackets
