Adding three-digit numbers to four-digit numbers can be a bit challenging, especially if you’re not used to working with larger numbers. However, with a bit of practice and some basic techniques, it’s a skill that can be easily learned.

The first step in adding three-digit numbers to four-digit numbers is to line up the digits in the two numbers so that the units digits are aligned, the tens digits are aligned, and so on. This will make it easier to keep track of the place values as you work through the problem.

Next, you’ll need to start with the units digits and work your way up through the tens and hundreds digits, carrying over any remainder as necessary. For example, if you’re adding the numbers 1,234 and 5,678, you would start with the units digits (4 and 8), which sum to 12. You would then carry over the 1 to the tens digits (3 and 6), which sum to 9, plus the 1 carried over, to give a result of 10. Finally, you would add the hundreds digits (2 and 5), plus the 1 carried over, to give a result of 8.

It’s important to keep track of the place values as you work through the problem, as this will help you ensure that you’re adding the correct digits together. For example, if you accidentally added the tens digits together instead of the units digits, you would end up with an incorrect result.

One helpful technique for adding three-digit numbers to four-digit numbers is to use columns to keep track of the place values. For example, you could set up the problem as follows, Then, you could add the digits in each column separately, carrying over any remainder as necessary : 1,234 +5,678 = 6,012.

It’s also helpful to use mental math techniques when adding three-digit numbers to four-digit numbers. For example, you could break the numbers down into smaller chunks, or use rounding to make the numbers easier to work with. For example, if you’re adding 1,234 and 5,678, you could round the numbers to 1,000 and 6,000, which would make the problem much easier to solve.

Overall, adding three-digit numbers to four-digit numbers requires a bit of practice and attention to detail. However, with some basic techniques and a bit of practice, it’s a skill that can be easily learned.
