Solve Vertical Addition: 57 + 2 Step by Step

To solve this problem, we will use vertical addition:

• Step 1: Write down the numbers as they are presented, ensuring digits are aligned:
• $\begin{array}{c} 57\\ + 2 \\ \hline \\ \end{array}$
• Step 2: Add the units column first, which contains 7 and 2:

$7 + 2 = 9$

• Step 3: Since there is no other digit in the tens column from the number 2, bring down the 5 as it is.
• Thus, the tens column remains the same: $5$.
• Step 4: Write down the final answer below the line:
• $\begin{array}{c} 57\\ + 2 \\ \hline 59 \\ \end{array}$

Therefore, the sum of 57 and 2 is $59$, which corresponds to the correct choice 1.
