Introduction 
What is Multiplication?
Multiplication is a faster way of adding the same number multiple times. Instead of writing 
4+4+4, we can simply write 3×4, which means "3 groups of 4."
What is Division?
Division helps us share things equally or find how many groups we can make. When we 
divide 12÷3, we're finding out how many items are in each group when 12 items are split into 
3 equal groups.
Real-Life Applications
We use multiplication and division every day! When buying multiple items, sharing treats 
with friends, or organizing things into groups, these operations help us solve problems 
quickly.

Multiplication and Division
Multiplication as Repeated 
Addition
When we multiply 3 × 4, we're actually 
adding 4 three times: 4 + 4 + 4 = 12.
Think of it as having 3 groups with 4 
items in each group, giving us a total of 
12 items.
Division as Equal Sharing
When we divide 12 ÷ 4, we're splitting 12 
items into 4 equal groups.
Each group will have 3 items. So 12 ÷ 4 = 
3.
Connection
Multiplication and division are opposite operations 3 they undo each other!
If 3 × 4 = 12, then 12 ÷ 4 = 3 and 12 ÷ 3 = 4.

What is 6 × 5?
Solution 
6 Groups of 5
When we have 6 groups with 5 items in each group, we get a total of 30 items.
Repeated Addition
5 + 5 + 5 + 5 + 5 + 5 = 30
The Answer
6 × 5 = 30
Check with Division
We can check our answer with division: 30 ÷ 5 = 6 and 30 ÷ 6 = 5
