Lesson: Introduction to Division

Hello and welcome to this video, introduction to division.
What we will do is take a look for some division problems and give you an explanation of the concept.
Here we have a problem,
18 : 2 = 9
18 is called the dividend, this number is being divided into.
2 is called the diviser, this is a number that exactly divide into the divident
9 is called quotient, this a result.

Lets take a look two more word that have to do with division,
1. Divisible. It means can be divided into.
We can say that 18 is divisible by 2 or 9.
2. Factor. Factor is when one number divide exactly into another number.
We can say 2 and 9 is the factor of 18

Example 1
15 : 3 =
15 as a divident
3 as a diviser
and we have to find the quotient
how many times the divise going to divident?
how many times this three going to 15?
we know 3 goes to 15, is five times, so the result is 5

Remember that divisions is the opposite operation of the multiplication operation.
So, when you learning on times tables, its also helping you to learn the division.

4 x 8 = 32
so, 32 : 8 = 4
32 : 4 = 8
It all works together.
