00:00 Solve

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

00:06 Let's start by adding ones with ones

00:13 We'll substitute the ones, add 1 to the tens

00:17 We'll add tens with tens, remember to add 1 to the calculation

00:28 We'll substitute in the tens place

00:34 We'll add hundreds with hundreds, substitute in the hundreds place

00:38 And this is the solution to the question

To solve this problem, we will perform vertical addition of the numbers 137 and 523:

Step 1: Add the ones place: $7 + 3 = 10$ . We write down 0 and carry over the 1 to the tens place.
Step 2: Add the tens place: $3 + 2 = 5$ , and include the carried over 1, totaling $5 + 1 = 6$ . We write down 6.
Step 3: Add the hundreds place: $1 + 5 = 6$ . We write down 6.

By following these steps, the sum of the numbers 137 and 523 is calculated as 660.

Therefore, the solution to the problem is indeed $660$ , which matches with choice 2 among the given options.
