Solve (+43) - (+15): Integer Subtraction with Positive Numbers

Q: Why do we write (+43) instead of just 43?

The parentheses with explicit signs help you see clearly whether each number is positive or negative. This becomes especially important when working with negative numbers later!

Q: What if the second number was bigger than the first?

If you had $ (+15) - (+43) $, you'd get -28. The result would be negative because you're taking away more than you started with.

Q: How is this different from regular subtraction?

It's exactly the same! The explicit positive signs in parentheses are just showing you that both numbers are positive. $ (+43) - (+15) = 43 - 15 $

Q: Why don't I get a negative answer here?

Since $ 43 > 15 $, you're subtracting a smaller positive from a larger positive. The result stays positive because you still have some left over!

Technique: $(+43) - (+15)$ becomes $43 - 15 = 28$
Check: Add result to subtracted number: $28 + 15 = 43$ ✓

Common Mistakes

Avoid these frequent errors

Adding instead of subtracting when seeing positive signs
Don't add $43 + 15 = 58$ just because both numbers are positive! The operation symbol (-) tells you what to do, not the signs of the numbers. Always follow the operation: subtract means find the difference.
