Numbers that would require regrouping in the ones place when added to 21 are any numbers from 9 to 19. When adding a number in this range to 21, the sum will exceed 30, necessitating regrouping in the ones place to carry over to the tens place. For example, when adding 19 to 21, the sum is 40, requiring regrouping.

How is regrouping for addition similar to regrouping for multiplication?
Regrouping for addition and multiplication both involve reorganizing numbers to simplify calculations. In addition, regrouping allows us to carry over values when sums exceed ten, while in multiplication, regrouping helps in breaking down larger numbers into more manageable parts, often using the distributive property. Both methods ultimately aim to make the computation process easier and more efficient. Additionally, both techniques highlight the importance of place value in achieving accurate results.
What two different pairs of decimal whose sum are 14.1one pair should involve regrouping?
One pair of decimals that sums to 14.1 is 9.6 and 4.5, where regrouping is not necessary. Another pair is 10.2 and 3.9, which requires regrouping when adding the tenths place (2 + 9 = 11, so we carry over 1 to the units place). Both pairs correctly total 14.1.
What is the other name of regrouping?
The other name for regrouping is "borrowing." This term is often used in arithmetic, particularly in subtraction, where values are exchanged between place values to simplify calculations. In addition, it can also refer to "carrying" when dealing with addition.
How do we regroup 1578 - 6000 only regrouping once?
To regroup 1578 - 6000 by regrouping once, we can first think of 6000 as 6000 = 5000 + 1000. Then, we can subtract 5000 from 1578, which requires regrouping since 1578 is less than 5000. By borrowing 1 from the thousands place, we turn 1578 into 6578 (which is 1000 more), allowing us to calculate 6578 - 5000 = 1578. Finally, we subtract the remaining 1000 to get 1578 - 6000 = -4222.
What is the greatest number you can add 457 without regroup in any place?
The greatest number you can add to 457 without regrouping in any place is 42. This is because, when adding 42 to 457, the digits in each column (units, tens, and hundreds) do not exceed the value of 9, thereby avoiding any regrouping. Specifically, 457 + 42 equals 499, which maintains the digits within their respective places.

What is regrouping in math?
EXAMPLE: 24+2= 26 NO REGROUPING 56+3=59 NO REGROUPING 24+8=32 IS REGROUPING 56+4=60 IS REGROUPING TAKING THE ONES PLACE ONLY: FIRST EXAMPLE 4+2=6 HAS TO BE LESS THAN 9 4+8=12 YOU MAKE 10 IN THE ONES PLACE YOU CARRY OVER WHICH NOW THEY ARE CALLING REGROUPING. WE JUST CALLED IT CARRYING OVER AND BORROWING. HOPE THIS HELPS.
What is greatest number you can add to 457 without having to regroup in any place?
I take this question to mean what number when added to 457 will yield 999. In this case it is 542.

What is the word to use place value to exchange equal amounts when renaming a number?
Ah, what a wonderful question! The word you're looking for is "regrouping." When we regroup in math, we move values between place values to make exchanging equal amounts easier. It's like rearranging puzzle pieces to create a beautiful picture of numbers. Just remember, there are no mistakes in math, only happy little accidents!
What is subrtacting with regrouping in whole numbers?
Back in the day, regrouping in addition was called "carrying" and regrouping in subtraction was called "borrowing." These problems might be easier to visualize if you copy them vertically. Example: 56 - 39 Just looking at it, you might think there's a problem with subtracting nine from six until you realize that 56 is 5 tens and 6 ones which is the same thing as 4 tens and 16 ones. Now you can subtract 9 from 16, leaving 7 in the ones place and 3 from 4, (the regrouped 5) leaving 1 in the tens place. 56 - 39 = 17

How do we regroup 1578 - 6000 only regrouping once?
To regroup 1578 - 6000 by regrouping once, we can first think of 6000 as 6000 = 5000 + 1000. Then, we can subtract 5000 from 1578, which requires regrouping since 1578 is less than 5000.

Why is it not necessary to line up the decimal point when multiplying two numbers?
Because the number of digits after the decimal place in a product does not require that.
When might i need to regroup more than one time?
You might need to regroup more than once when performing multi-digit addition or subtraction, especially when the sum or difference of two numbers exceeds the place value of the column you are working in. For example, when adding numbers like 456 and 378, regrouping may be required in both the tens and hundreds columns. Similarly, when subtracting numbers like 804 and 297, regrouping may be necessary multiple times to ensure accurate results.
What is the greatest number you can add 457 without regroup in any place?
The greatest number you can add to 457 without regrouping in any place is 42. This is because, when adding 42 to 457, the digits in each column (units, tens, and hundreds) do not exceed the value of 9, thereby avoiding any regrouping. Specifically, 457 + 42 equals 499, which maintains the digits within their respective places.
