Breaking down numbers makes addition easier and less error-prone! Adding 10 first gives you 8456, then adding 9 gives the final answer. This method helps you avoid mistakes with carrying.
Yes! Addition is commutative, meaning 8446 + 19 = 19 + 8446. The order doesn't matter - you'll get the same answer either way.
Write the numbers vertically with ones under ones, tens under tens, etc. This helps you see each column clearly:
8446
+ 19
------
Look at each column from right to left. If the sum in any column is 10 or greater, you need to carry 1 to the next column. In this problem, 6+9=15, so carry the 1.
Use estimation! Round 8446 to 8450 and 19 to 20. Then 8450 + 20 = 8470. Your exact answer of 8465 should be close to this estimate.
