## Carrying/Regrouping Numbers in Multiplication

In multiplication, you will need to carry/regroup a number whenever the value of the product is greater than nine. Today, many teachers are using the term regrouping, rather than carrying. Don’t let this trip you up- it is the same concept!

Carrying/Regrouping

**Step 1:** Stack the numbers so the larger is on top, aligning the numbers according to place value. (Tip: for more information, please see the Homework Unlocked video “Finding Place Value“.)

**Step 2:** Multiply the smaller number by each number in the larger number

For example, a problem such as **18 x 6** would require us to “carry” the 4 from the ones place (because 8 x 6 = 48) to the tens place. Since this numeral 4 really represents the number 40, it’s more appropriate to say we are *regrouping* it by representing those forty ones, as four tens.

**Example**: 18 x 6
