Q: How do you calculate 6/2(1+2) or 48/2(9+3)? What’s the deal with this orders of operation business?

The “order of operations” tells us the sequence in which we should carry out mathematical operations. Next, multiplication and division get carried out from left to right. Finally, additions and subtractions get carried out from left to right. These all stand for “Parenthesis, Exponents, Multiplication and Division, Addition and Subtraction”. When in doubt about what the orders of operation are for an expression, there is a simple solution which works even better than tattooing PEMDAS to your face.
