Step-by-Step Guide to Adding 3-Digit Numbers Without Regrouping

Understanding the Numbers

When adding 3-digit numbers, it's crucial to break them down into hundreds, tens, and ones. Let's look at an example with the numbers 327 and 251.

  • 327: This number has three hundreds, two tens, and seven ones.Hundreds place: 3
    Tens place: 2
    Ones place: 7

  • 251: This number has two hundreds, five tens, and one one.Hundreds place: 2
    Tens place: 5
    Ones place: 1


Adding the Ones

Start with the ones place:

  • 7 (ones from 327) + 1 (one from 251) = 8 ones


Adding the Ten

Next, add the tens place:

  • 2 (tens from 327) + 5 (tens from 251) = 7 tens


Adding the Hundreds

Finally, add the hundreds place:

  • 3 (hundreds from 327) + 2 (hundreds from 251) = 5 hundreds


Putting It All Together

When you combine all these, you get:

  • Hundreds: 5

  • Tens: 7

  • Ones: 8

So, 327 + 251 equals 578.
