If you have an order of operation math problem and it has subtraction and addition

Hello!

When using the order of operations, the sequence for solving equations is:
1) Numbers in parentheses
2) Numbers with exponents
3) Multiplications and divisions
4) Addition and subtractions

If the math problem only contains additions and subtractions, you will complete it in the order of the problem (from left to right).
For example, if the problem is 5+2-3, you would do it in sequence:
5+2-3= 7-3
7-3= 4

I hope this helps answer your question! Have a great day!
