Solve the Addition Expression: 9 + 2 + 5

Q: Do I have to add from left to right?

While addition is commutative (you can add in any order), adding from left to right helps you stay organized and avoid mistakes. It's the standard way to solve addition problems.

Q: Can I add the numbers in a different order?

Yes! You could do $2 + 5 = 7$ first, then $9 + 7 = 16$. The answer will be the same because addition follows the commutative property.

Q: How can I check my answer without redoing the problem?

Try counting up from the largest number! Start at 9, then count 2 more: 10, 11. Then count 5 more: 12, 13, 14, 15, 16. You should get the same answer!

Q: Is there a faster way to solve this?

With practice, you might recognize number bonds like $2 + 5 = 7$, then quickly calculate $9 + 7 = 16$. But the step-by-step method always works reliably!

Common Mistakes

Avoid these frequent errors

Adding all three numbers at once without steps
Don't try to add 9 + 2 + 5 all together in your head = confusion and wrong answers! This leads to mixing up numbers and calculation errors. Always add two numbers first, then add the third number to that result.
