I know of someone who does not understand the PEMDAS method of solving math equations. What is the best way to explain this to her.

You could probably explain it to her by using an example:

"Here’s an example, let’s say you wanted to multiply 15 × 8. How would you do that?"

It sounds like PEMDAS, pronounced “PEHM-daz”, is a common method for solving certain types of math equations, right? You could teach it to her by starting with easy equations and working your way to more difficult ones. A full explanation can be found in the Wikipedia article about it, or you could link to the full article here.
