Do you need to regroup to find 73-35? Explain your answer.
Yes. How else would subtract 5 from 3?
73-35
Yes, regrouping is needed to find 73 - 35. In order to understand why, let's break down the subtraction process.
When we subtract two numbers, we start from the rightmost digits and work our way to the left. In this case, we have 73 - 35.
Starting from the right, we subtract 5 from 3. However, 5 is greater than 3, so we cannot directly subtract these two digits. This is where regrouping becomes necessary.
To regroup, we borrow a value from the next digit to the left. In this case, we borrow 1 (from the tens place) and add it to the 3, making it 13. Now we have 13 - 5, which equals 8.
Next, we move on to the next digits. We subtract 3 from 7, which gives us 4.
Now we can combine the two results: 73 - 35 = 38.
In conclusion, regrouping is needed when the digit being subtracted is greater than the corresponding digit being subtracted from.
