Thank you for the opportunity to help you with your question!

1.Having understood order of operations, know that addition comes first before subtraction.

2. Understand that the sign (+ or -) before each number is the one defining it, and the number without a sign is + (positive) by default.

3. + and + means you add,   - and - means you add

4. + and - means you subtract.
