For math class, I am having a lot of trouble with adding and subtracting negative and positive numbers. I just need to know the basics of this.
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.
