This can help students learn how to quickly work through problems. For making one addend the next tens number, students can use their knowledge of place value to add the numbers mentally. For example, if the two numbers are 30 and 40, the student can break down the problem into smaller pieces and add the tens and ones together. This would result in 7 tens, or 70.

## Using a Calculator Using a calculator is another way students can approach this type of problem. A calculator can be used to quickly add two numbers that are in the tens. This is a great option for students who are struggling with the mental math approach or if they need to check their work. With a calculator, students can simply enter the two numbers and the calculator will display the sum of the two numbers. For example, if the two numbers are 30 and 40, the student can enter 30 + 40 into the calculator and the result will be 70.

## Conclusion Making one addend the next tens number is a common math problem that students need to learn how to solve. There are several different ways to approach this type of problem, such as using place value, mental math, and a calculator.
