solve the top and bottom first
We have to use the order of operations so everyone solves a problem the same.
To Evaluate expressions using the order of operations where there are fraction bars, simplify the top and bottom first, then divide.
how do you use order of operations
No professions use order of operations. It is just a method of solving an equation.
Because if you perform the operations in a different order your answer will be wrong.
You use order of operations in equations that have more than one type of operation going on (for example, an equation with parenthesis, addition, and multiplication). You would use order of operations in equations like that so you know which operation to do first.
You don't.
The order of operations (BIDMAS/PODMAS) does not change except that you need to remember that there are implied divisions in each fraction.
The PEMDAS acronym has been in use for the order of operations in mathematics for several decades.
Multiplication
Use brackets or parentheses.
