Solve Vertical Addition: 86 + 11 Step-by-Step

To solve the given problem, we will perform vertical addition:

• Step 1: Align the numbers by their rightmost digits:
  $\begin{aligned} &86 \\ +& \\ &11 \\ &\underline{\phantom{776}} \\ \end{aligned}$
• Step 2: Add the digits in the units column:
  - The units digits are 6 and 1. Adding them gives us $6 + 1 = 7$.
• Step 3: Add the digits in the tens column:
  - The tens digits are 8 and 1. Adding them gives us $8 + 1 = 9$.
• Step 4: Combine the results:
  - Write down the addition result starting with the tens followed by the units to get the final sum of 97.

Thus, the result of the addition is $97$.

Since this problem requires a choice, the correct choice from the given options is: : $97$
