Study Notes
Adding numbers without regrouping
- When adding numbers, start by adding the ones place, then tens, hundreds, thousands, and finally ten thousands.
- Align the digits with the same place value when adding numbers vertically.
Example 1: Adding horizontally
- 68 942 + 30 051 = 98 993
- Add ones: 2 + 1 = 3
- Add tens: 4 + 5 = 9
- Add hundreds: 9 + 0 = 9
- Add thousands: 8 + 0 = 8
- Add ten thousands: 6 + 3 = 9
Example 2: Adding vertically
- 45 248 + 20 231 = 65 479
- Add ones: 8 + 1 = 9
- Add tens: 4 + 3 = 7
- Add hundreds: 2 + 2 = 4
- Add thousands: 5 + 0 = 5
- Add ten thousands: 4 + 2 = 6
Adding numbers with regrouping
- If the sum of the digits in a place value is 10 or more, regroup the excess into the next place to the left.
- For example, if the sum of the ones is 12, write 2 in the ones position and regroup 10 ones as 1 ten.
Example 2: Adding vertically with regrouping
- 13 827 + 15 685 = 29 512
- Add ones: 7 + 5 = 12, write 2 in the ones place, regroup 1 ten
- Add tens: 1 + 2 + 8 = 11, write 1 in the tens place, regroup 1 hundred
- Add hundreds: 1 + 8 + 6 = 15, write 5 in the hundreds place, regroup 1 thousand
- Add thousands: 1 + 3 + 5 = 9, write 9 in the thousands place
- Add ten thousands: 1 + 1 = 2, write 2 in the ten thousands place
Example 3: Adding vertically with regrouping
- 31 072 + 29 853 = 60 925
- Add ones: 2 + 3 = 5
- Add tens: 7 + 5 = 12, write 2 in the tens place, regroup 1 hundred
- Add hundreds: 1 + 0 + 8 = 9
- Add thousands: 1 + 9 = 10, write 0 in the thousands place, regroup 1 ten thousand
- Add ten thousands: 1 + 3 + 2 = 6
Summary
- To add two or more numbers, align the digits horizontally or vertically.
- Add the digits of the numbers from right to left.
- Remember to regroup when the sum in a place value is 10 or more.
