Multiplication is nothing but adding the same number again and again. The result is called "PRODUCT". the two numbers that are multiplied are called "Factors".
When we multiply 5 by 3, we get 15, Right?
In short, we write 5 × 3 = 15. Here, 5 and 3 are called the Factors and 15 is the Product.
Example
3 × 7 = 21, 3 × 7 is factors and 21 is product.
Factors  Product 
3 , 7  21 
Example 1:Find the product of 3 and 10.
Solution: 3 × 10 = 30. The product is 30.
Example 2: Find the missing factor:_______ × 6 = 30.
Solution: We can easily find out from the table of 6 that the missing factor is 5. It is so because 5 × 6 = 30.
Example 3:Sekhar and his friends had come to watch a Basketball game in which Sekhar's brother Mahesh was playing.Mahesh has scored 25 points in each of the last 4 games!!. How many points he scored altogether in 4 games?
Solution: Altogether, Mahesh has scored (25+25+25+25) points=100 points.
This is the same as 25 × 4, as multiplication means repeated addition.

Answer:100 points
 Multiply the ones
 Multiply the tens
 Multiply the Hundreds
 Regroup tens and hundreds
 Add them all to get the Product
 In three digit number, we know we have ones place, tens place and Hundreds place.
When multiplying:
Example: Multiply 243 by 3.
Solution:
Step 1: multiply the ones.
3 × 3 ones = 9 ones
Step 2: Multiply the tens.
4 × 3 tens = 12 tens.
Regrouping is needed.
12 tens = 1 hundred and 2 tens
Write 2 in the tens column and carry 1 to the hundreds column.
Step 3: Multiply the hundreds.
2 × 3 hundred = 6 hundreds
6 hundreds + 1 hundred (carried over) = 7 hundreds
Write 7 in the hundreds column.

Look at ten table; same as one table except zeros in ones place! Now we know we are experts in one and ten tables!!
1 × 10 = 10  2 × 10 = 20  3 × 10 = 30  4 × 10 = 40  5 × 10 = 50 
6 × 10 = 60  7 × 10 = 70  8 × 10 = 80  9 × 10 = 90  10 × 10 = 100 
To multiply the numbers by 10, we write a zero in the ones place and multiply the other numbers.
What about multiplication by 20,30,40 and so on?42 × 20 = 840
11 × 80 = 880
15 × 90 = 1350
 The number to be multiplied is known as the multiplicand.
 The number by which the multiplicand is multiplied is called the multiplier.
 The answer we get is called the product.
Example: 3 × 100 = 300
5 × 200 = 1000
12 × 300 = 3600
In a multiplication sum,
Multiplying by a 2Digit Multiplier
We have learnt multiplying with 1 digit multipliers. Now, we shall learn to multiply by 2 digit multipliers.
Example: In a cricket stadium the north stand has 23 rows with 16 seats in each row. How many seats are there in the stand?
Solution: Here, the multiplier is 16.
We can write 16 as 16 =10+6.
Therefore, multiply 23 by 10 and 6 separately, and add the two products which will give the final product.
23×6=138 and 23×10=230
Therefore, 23×16=23(6+10)=(23×6)+(23×10)=138+230=368.
