Solve Addition Problem: (+8) + (+12) with Positive Numbers

Q: Why do we write (+8) instead of just 8?

The parentheses with signs help us see the sign of each number clearly. This becomes really important when we mix positive and negative numbers in the same problem.

Q: Is there a difference between +8 and (+8)?

No difference at all! Both mean positive 8. The parentheses are just used to make the signs extra clear when we're learning about integer operations.

Q: How do I visualize this on a number line?

Start at 8 on the number line. Since you're adding a positive 12, move 12 steps to the right. You'll land on 20!

Q: What's the fastest way to solve this?

Simply ignore the parentheses and add normally: 8 + 12 = 20. The parentheses don't change anything when both numbers are positive!
