Back in the day, regrouping in addition was called "carrying" and regrouping in subtraction was called "borrowing." I think "regrouping" is a better term for all of it. 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

Example: 45 + 28

5 + 8 is 13, which won't fit in the ones place, so we leave 3 of the ones there and regroup the ten other ones into one ten which we add in the tens column. 1 + 4 + 2 = 7

45 + 28 = 73

I need help with that. I happen to have that question now in my Math lesson :( HELP!!!

Regrouping simply means putting the 2+ answers into a group and subtracting all the answers together.

No. you would use cubes only if you were trying to find the perimeter, area, or volume of a dimensional shape.

Regrouping in math with decimals simply refers to the term used addition or subtraction when either carrying or borrowing is involved.

During the math lesson, the students had to practice regrouping numbers to solve addition problems.

Regrouping simply means putting the 2+ answers into a group and subtracting all the answers together.

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.

The two different pairs of decimals whose sums are 14.1 and one pair involves regrouping on math are 8.4 and 5.7.
