FAQs on Adding Whole Tens to 2-Digit Numbers – Find the Missing Number

1. How do you find the missing number in these addition problems?

To find the missing number when adding whole tens, you can use subtraction or count the tens. The easiest method is to look at the digit in the tens place and see how much it has increased.

Example Problem: 26 + ___ = 56.
Step 1: Look at the sum (56) and the known addend (26).
Step 2: Subtract the smaller number from the larger number: 56 - 26 = 30.
Step 3: The missing number is 30, which is a whole ten.

2. What is the best way to add whole tens to a 2-digit number?

The best way to add whole tens (like 10, 20, 30) to a 2-digit number is by focusing only on the tens place. The digit in the ones place does not change.

For instance, to solve 34 + 20:
Identify the digit in the tens place of 34, which is 3.
Add the tens from 20 (which is 2 tens) to it: 3 + 2 = 5.
Keep the ones digit the same (4).
The answer is 54. This is a key skill in 2-digit number addition.
