Explain two different ways to solve 724.

Answer 1

1. One way to solve 724 is to break it down into its place values. In this case, 724 can be broken down into 700 + 20 + 4. Add these three numbers together to get the total sum: 700 + 20 + 4 = 724.

2. Another way to solve 724 is by using the column addition method. Write the numbers 724 and 0 under each other with the ones digits lined up. Start by adding the ones digits: 4 + 0 = 4. Write down the 4 below the line. Then, move to the next column and add the tens digits: 2 + 0 = 2. Write down the 2 below the line. Finally, move to the hundreds column and add the hundreds digits: 7 + 0 = 7. Write down the 7 below the line. The final sum is 724.
