Question

This is a question from my sibling's math class.

Answer 1

Answer:

14

Step-by-step explanation:

You can solve using PEMDAS:

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

3(2+5)-5(3)+8=?

3(7)-5(3)+8=?

No exponents

3(7)-5(3)+8=?

21-15+8=?

No division

21-15+8=?

21-7=?

21-7=14

3(2+5)-5(3)+8=14

Answer 2

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.
