Order of Operations (PEMDAS) — Definition & Examples

Hungry Jack is enjoying an all-you-can eat pancake buffet at Peppy's Pancake House in celebration of National Pancake Day (March 5). He starts by taking two plates to the buffet table, and puts $5$ pancakes on one plate, and $4$ on the other. Then he returns to his seat and eats them all.

After pausing for a moment to let his food digest, he goes back to the buffet table with his two plates. He gets the same stacks of pancakes $3$ more times, eating all of the pancakes he takes, except for $2$ off of the very last plate.

How many pancakes did Hungry Jack eat in total?
