Solve Two-Digit Addition: 53 + 68 Using Column Method

$\begin{aligned} &53 \\ +& \\ &68 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we'll add the numbers 53 and 68 using vertical addition. Follow these steps:

Step 1: Align the numbers vertically by place value:

\begin{aligned} &53 \\ + &68 \\ \end{aligned}

Step 2: Add the units digits (rightmost column):

$3 + 8 = 11$

• The result is 11. Write down 1 in the units column, and carry over 1 to the tens column.

Step 3: Add the tens digits (leftmost column), including the carry:

$5 + 6 + 1 = 12$

• Write down 2 in the tens column, and carry over 1 to the hundreds column. This gives us a final result:

\begin{aligned} &121 \\ \end{aligned}

Therefore, the correct answer is $121$.
