To solve this problem, we'll follow these steps:
Let's work through these steps:
Step 1: Add the units digits, which are 7 and 2.
.
Since 9 is less than 10, we don't need to carry over to the tens column.
Step 2: Add the tens digits, which are 4 and 2.
.
Combine these results: The sum of 47 and 22 is 69.
Therefore, the solution to the problem is .
69
\( \begin{aligned} &83 \\ +& \\ &~~6 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
Lining up numbers by place value ensures you're adding the right digits together! Ones go with ones, tens with tens. Without proper alignment, you'll get the wrong answer every time.
This is super common! If you add 4 + 7 = 11 instead of 4 + 2 = 6, you'll get the wrong tens digit. Always double-check that you're adding digits in the same column.
Yes! Always start with the rightmost column (ones place) and work left. This helps you handle any carrying that might be needed in more complex problems.
Try adding the numbers in a different order: . You should get the same answer! You can also count up from the larger number or use a calculator to verify.
The horizontal line separates the problem from the answer. Everything above the line gets added together, and the sum goes below the line.
