Ответ:
Quick explanation:
Brief explanation: To add two numbers, we align them vertically by place value and add each column starting from the right, carrying over when a sum exceeds 9.
Step-by-step solution:
- Step 1: Add the ones column: 9 + 9 = 18. Write down 8 and carry over 1 to the tens column.
- Step 2: Add the tens column: 3 + 8 + 1 (carry-over) = 12. Write down 2 and carry over 1 to the hundreds column.
- Step 3: Add the hundreds column: 2 + 5 + 1 (carry-over) = 8.
