What is the difference between 50 and 29?

To find the difference between two numbers, you subtract the smaller number from the larger number. In this case, we want to find the difference between 50 and 29.

Start by performing the subtraction:

50 - 29.

When you perform this calculation:

1. Subtract the ones place: 0 (from 50) minus 9 (from 29) cannot be done, so you need to regroup. This means you take 1 from the tens place (making it 4 instead of 5), and now the ones becomes 10.

2. Now subtract: 10 - 9 = 1.

3. Next, subtract the tens place: 4 - 2 = 2.

Putting it all together gives you the final answer: 21.

This means the difference between 50 and 29 is 21, which corresponds to the answer option. Understanding how to perform subtraction, especially when regrouping is necessary, is crucial in solving such problems accurately.
