Solve the Addition Expression: 31 + 8 + 14

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

Not necessarily! Addition is commutative, so you can add in any order. You could do 8 + 14 = 22, then 31 + 22 = 53. The result will be the same!

Q: What's the easiest way to add three numbers?

Look for friendly pairs that make round numbers! Sometimes 8 + 14 = 22 might be easier to calculate first, then add 31 to get 53.

Q: How can I check if 53 is correct?

Try adding in a different order: $ 8 + 14 + 31 = 22 + 31 = 53 $. If you get the same answer, you're right!

Q: What if I keep getting different answers?

Slow down and double-check each step. Write down each partial sum: 31 + 8 = ? (check this first), then add 14 to that result.

Q: Is there a shortcut for adding multiple numbers?

Look for numbers that add to 10 or multiples of 10! In this case, there's no obvious shortcut, but the step-by-step method is reliable and prevents errors.
