Answer:

3(2+5) - 5(3) + 8\\3(7) - 15 + 8\\21 - 15 + 8\\6 + 8\\14

Step-by-step explanation:

The reason PEMDAS is in the order it is, is because we need to simplify all the operations into addition before combining everything. Think about it, mulitplication is just another way to add large quantities of things quickly, same with exponents.
