00:00 Solve

00:03 Each time calculate the sum of 2 digits, and then substitute

00:06 Let's start by adding ones with ones, substitute the solution

00:09 Put 0 where there is no number

00:12 Add tens with tens, substitute the solution

00:15 And this is the solution to the question

To solve this problem, we will follow these steps:

Step 1: Align the numbers vertically with the units digits under each other: $31$ and $6$ .
Step 2: Add the units digits: $1 + 6 = 7$ . There is no carryover in this simple addition.
Step 3: The tens digit from the number 31, which is $3$ , remains unchanged as there is no carry that affects this place value.
Step 4: Write down the result of the addition, which is $37$ .

Therefore, the sum of $31$ and $6$ is $37$ .

The correct answer is choice 1: $37$ .
