Solve Vertical Addition: 75 + 10 Step by Step

To solve this problem, we'll use vertical addition. Let's follow these steps to ensure accuracy:

• Step 1: Align the two numbers vertically by their place values. The given numbers are 75 and 10. Write 75 on top and 10 below it, making sure that the digits are aligned in the correct columns:

• Step 2: Add the digits in the units column (the rightmost column). This means adding 5 (from 75) and 0 (from 10):
  $5 + 0 = 5$
• Step 3: Move to the tens column (the next column on the left). Add 7 (from 75) and 1 (from 10):
  $7 + 1 = 8$
• Step 4: Combine the results from each column to form the sum. Since there are no carries, the direct sum of the columns is:
  $\begin{array}{c} 75 \\ +10 \\ \underline{85} \end{array}$ The resulting sum is 85.

Therefore, the solution to the problem is $85$.
