What is the sum of 12 and 15?

To find the sum of 12 and 15, you simply add the two numbers together.

Start with the first number, which is 12. When you add 15 to it, you can do this in steps for clarity:

• First, you can add 10 to 12, which gives you 22.

• Then, add the remaining 5 to 22.

So, 22 + 5 equals 27. Therefore, the correct total, or the sum of 12 and 15, is 27. This total clearly shows why adding these two numbers results in the specific sum determined by the math process.

Understanding the process of addition can be useful not just for this specific question but for many similar problems you may encounter.
