Adding one-digit and two-digit numbers is a fundamental math skill that is essential for success in elementary and middle school math. It is a basic building block for more advanced math concepts, such as carrying and borrowing, and it is also used in everyday life for tasks such as shopping and budgeting.

To add one-digit and two-digit numbers, you first need to understand place value. Place value is the value of each digit in a number based on its position. For example, in the number 53, the 5 is in the tens place, which means it has a value of 50. The 3 is in the ones place, which means it has a value of 3.

To add one-digit and two-digit numbers, you need to line up the numbers by place value, just like you would with columns in a spreadsheet. The ones place is on the right, the tens place is in the middle, and the hundreds place (if there is one) is on the left.

For example, to add the numbers 23 and 5, you would line them up like this:

23 + 5

Then you can start adding from the right side, working your way to the left. You start with the ones place and add 3 + 5 to get 8. Since 8 is greater than 9, you need to carry the 1 to the tens place. This is done by writing the 1 above the tens place and subtracting it from the 8 to get the final result in the ones place, which is 8 - 1 = 7.

In the tens place, you add 2 + 1 (the carried over 1 from the ones place) to get 3. The final result is therefore 27.

If you are adding more than two numbers, you can use the same process by starting with the ones place and working your way to the left. For example, to add the numbers 48, 23, and 15, you would line them up and add them like this:

It is important to remember to carry over any digits when necessary, and to line up the numbers correctly by place value. With practice, adding one-digit and two-digit numbers will become second nature and you will be able to do it quickly and accurately.

In summary, adding one-digit and two-digit numbers involves understanding place value, lining up the numbers by place value, and carrying over digits when necessary. It is a fundamental math skill that is essential for success in math and in everyday life.
