The method: 47 + 38
- Line up the numbers: units under units, tens under tens.
- Add the units: 7 + 8 = 15. Write 5 and carry 1 to the tens column.
- Add the tens plus the carry: 4 + 3 + 1 = 8.
- Result: 47 + 38 = 85.
Step 1
The exercise starts with 47 and 38 lined up. Begin with the units.
Step 2
7 + 8 = 15: write 5 in the units column.
Step 3
The carry 1 is placed above the tens column.
Result
4 + 3 + 1 = 8. The final result is 85.
