Question

$\begin{aligned} &65 \\ +& \\ &~~4 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

00:00 Solve

00:03 Each time consider combining 2 digits, and then place

00:06 Let's start by combining units with units, place the solution

00:09 Place 0 where there is no digit

00:12 Combine tens with tens, place the solution

00:15 And this is the solution to the question

To solve this problem, we'll perform vertical addition of the numbers 65 and 4:

Step 1: Align the numbers vertically with the digits correctly placed (units under units, tens under tens).
Step 2: Start with the rightmost digits (the units place). Add the units: $5 + 4 = 9$ .
Step 3: No carrying is necessary as the sum is less than 10.
Step 4: Move to the tens place. Since we're adding a single-digit number, only the left number (6 in the tens place) remains as it is.

Combining these, the result of $65 + 4$ is $69$ .

Thus, the correct answer is $69$ .
