# Division as equal groups

Sal represents division as equal groups of objects.

• Since multiplication is repeated addition, is division also repeated subtraction?
• Good question! In a way, we can think of division as counting how many times we would need to subtract the divisor, starting from the dividend, to get to 0.

For example, for the problem 12 divided by 3 (or 3 into 12), we would need to subtract 3 four times from 12 to get to 0:
12-3=9, 9-3=6, 6-3=3, and 3-3=0.

Also in long division problem, every digit in the answer involves a subtraction step. This, in a way, can be thought of as repeated subtraction.

• Why do we need to learn division?
• Example: Suppose you need to read a 63-page book in 7 days. You plan to read the same number of pages each day. You want to know how many pages to read each day. Then you would divide 63 by 7, to get 9 pages each day.

This is just one of many situations where you would need to divide numbers.

In higher levels of math such as algebra and geometry later on, you will need to know division.

Have a blessed, wonderful day!
• Does that mean that 3 x 4 = 12?
• Yes because 12/4=3 and 12/3=4
• what is division in as a subject
• go to FAQ you will see there!
• can we learn? about times and divsion?
• How many ansers are there.
• many and more!
