How do you know that 4+7•3 equals 25 not 33

PEMDAS/Order of Operations

Step-by-step explanation:

Order of Operations, or PEMDAS states that you must solve mathematics in the following order:

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Instead of completing 4+7•3 by going left to right, follow the order of PEMDAS.

Multiplication is the first operation in PEMDAS that is in the problem, so do that first (4+21)

Now you can add and your answer should be 25 :)
