How do you explain the MDAS or Pemdas rule?
PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction. For any expression, all exponents should be simplified first, followed by multiplication and division from left to right and, finally, addition and subtraction from left to right.
How do you explain order of operations?
The order of operations tells us the order to solve steps in expressions with more than one operation. First, we solve any operations inside of parentheses or brackets. Second, we solve any exponents. Third, we solve all multiplication and division from left to right.

How does the order of operations help solve one and two step equations?
The order of operations' set of rules can be applied to one step and two step operations in order to isolate the variable by manipulating the expression using the reverse order of operations on both sides of the equation (the opposite) to undo whatever operation being applied to the variable.
When did order of operations start?
"I suspect that the concept, and especially the term "order of operations" and the "PEMDAS/BEDMAS" mnemonics, was formalized only in this century, or at least in the late 1800s, with the growth of the textbook industry.
