Multiplication as Repeated Addition
Multiplication is a faster way to add the same number again and again. When you add 3 + 3 + 3 + 3, you are adding 3 four times. Instead, you can say 4 times 3 or write 4 × 3 = 12.
This idea is called multiplication as repeated addition. It is the very first step in learning multiplication.
What is Multiplication as Repeated Addition - Class 2 Maths (Multiplication Introduction)?
Multiplication is adding the same number over and over.
Repeated Addition: 5 + 5 + 5 = 3 × 5 = 15
Here, 5 is added 3 times. So we write it as 3 × 5.
Key words:
- Groups of: "4 groups of 3" means 3 + 3 + 3 + 3 = 4 × 3 = 12
- Times: "5 times 2" means 2 + 2 + 2 + 2 + 2 = 5 × 2 = 10
Solved Examples
Example 1: Example 1: Write as multiplication
Question: Write 4 + 4 + 4 as a multiplication.
Think:
- The number 4 is added 3 times
- 3 groups of 4
Answer: 4 + 4 + 4 = 3 × 4 = 12.
Example 2: Example 2: Write as repeated addition
Question: Write 5 × 2 as repeated addition.
Think:
- 5 × 2 means 2 added 5 times
- 2 + 2 + 2 + 2 + 2
Answer: 5 × 2 = 2 + 2 + 2 + 2 + 2 = 10.
Example 3: Example 3: Ria’s flower pots
Question: Ria has 3 flower pots. Each pot has 5 flowers. How many flowers in all?
Think:
- 3 groups of 5 flowers
- 5 + 5 + 5 = 15
- Or: 3 × 5 = 15
Answer: Ria has 15 flowers in all.
Example 4: Example 4: Mangoes on plates
Question: There are 4 plates. Each plate has 2 mangoes. How many mangoes in total?
Think:
- 4 groups of 2
- 2 + 2 + 2 + 2 = 8
- Or: 4 × 2 = 8
Answer: There are 8 mangoes in total.
Example 5: Example 5: Skip counting connection
Question: Skip count by 3: 3, 6, 9, 12, 15. How is this like multiplication?
Think:
- 1st number: 1 × 3 = 3
- 2nd number: 2 × 3 = 6
- 3rd number: 3 × 3 = 9
- 4th number: 4 × 3 = 12
- 5th number: 5 × 3 = 15
Answer: Skip counting by 3 is the same as the multiplication table of 3.
Example 6: Example 6: Aman’s cricket teams
Question: There are 6 cricket teams. Each team has 10 players. How many players in all?
Think:
- 6 groups of 10
- 10 + 10 + 10 + 10 + 10 + 10 = 60
- Or: 6 × 10 = 60
Answer: There are 60 players in all.
Example 7: Example 7: Zero groups
Question: What is 0 × 5?
Think:
- 0 groups of 5 means no groups at all
- Nothing is added
- 0 × 5 = 0
Answer: 0 × 5 = 0.
Key Points to Remember
- Multiplication is repeated addition: adding the same number again and again.
- 3 × 4 means “3 groups of 4” = 4 + 4 + 4 = 12.
- Skip counting by a number is the same as its multiplication table.
- Any number × 0 = 0 (zero groups means nothing).
- Any number × 1 = the number itself (one group).
- Multiplication makes counting large equal groups much faster than addition.
Practice Problems
- Write 6 + 6 + 6 + 6 as a multiplication.
- Write 4 × 5 as repeated addition and find the answer.
- There are 5 bags with 10 apples each. How many apples in all?
- What is 7 × 2 using repeated addition?
- Write the multiplication for: 3 + 3 + 3 + 3 + 3.
- Priya has 8 boxes. Each box has 2 pencils. How many pencils in total?
Frequently Asked Questions
Q1. What is multiplication as repeated addition?
It means adding the same number over and over. 3 + 3 + 3 + 3 (four times) is the same as 4 × 3 = 12. Multiplication is a shortcut for repeated addition.
Q2. How do I read 4 × 3?
Read it as "four times three" or "four groups of three." It means 3 + 3 + 3 + 3 = 12.
Q3. Is 3 × 4 the same as 4 × 3?
Yes, the answer is the same: 12. But the meaning is slightly different. 3 × 4 means "3 groups of 4" and 4 × 3 means "4 groups of 3."
Q4. How is skip counting related to multiplication?
Skip counting by 5 gives: 5, 10, 15, 20, 25... These are the same as 1×5, 2×5, 3×5, 4×5, 5×5. Skip counting IS the multiplication table.
Q5. What is any number multiplied by 0?
Zero. 0 × 5 = 0, because zero groups of 5 means nothing at all.
Q6. What is any number multiplied by 1?
The number itself. 1 × 5 = 5, because one group of 5 is just 5.
