What Is Multiplication?
Multiplication: Repeated addition is to add equal groups or the same number over and over. Multiplication is the repetitive addition.Multiplicand: The number that is to be multiplied is called the multiplicand.
Multiplier: The number with which we multiply is called the multiplier.
Product: The number that is obtained as the result of multiplication is called the product.
Grid Method Multiplication:
 Grid method is the method to multiply the number by portioning it into simpler place value.
 It is also known as box method.
Multiplication Rules of 3digit and 1digit numbers using the grid method
Step 1: Expand the first number as
hundreds, tens, and ones within the grid.
Step 2: Multiply each digit of the first
number by the second number. Write all the products within the grid.
Step 3: Add all the obtained product
outside the grid.
Example:
Multiply 346 by 6 using the grid method.
Solution:
Therefore, 346 × 6 = 2076.
2 Digit Multiplication using the grid method
Step 1: Expand the first number as tens
and ones within the grid.
Step 2: Expand the second number as tens
and ones within the grid.
Step 3: Multiply each digit of the first
number by each digit second number. Write all the products within the grid.
Step 4: Add all the obtained product
outside the grid.
Example:
Multiply 28 by 24 using the grid method.
Solution:
Therefore, 24 × 28 = 672.
Multiplication Rules of 3 or 4Digit Numbers by 1Digit Number:
Step 1: Write the multiplicand on the top
Step 2: Write the multiplier below it.
Step 3: Multiply each digit of the
multiplicand by the multiplier starting from the extreme right.
Step 4: Write the product below the
horizontal line. If the product is more than 9 then carry the ten digits to
the next column.
Example:
Multiply 354 by 7.
Solution:
3Digit by 2Digit Multiplication:
Step 1: Write the multiplicand on the top.
Step 2: Write the multiplier below it.
Step 3: Multiply the unit digit of the
multiplier by each digit of the multiplicand. If the product is more than 9
then carry the ten digits to the next column.
Step 4: Write the product below the
horizontal line.
Step 5: Place a 0 below the last digit of
the obtained productMultiply the tens digit of the multiplier by each digit
of the multiplicand. If the product is more than 9 then carry the ten digits
to the next column.
Step 6: Multiply the tens digit of the
multiplier by each digit of the multiplicand. If the product is more than 9
then carry the ten digits to the next column.
Step 7: Add both the obtained products.
Example:
Multiply 213 by 27.
Solution:
Write 213 on the top and 27 below it.
Properties of Multiplication:
 If a number is multiplied by 0 then the product is 0.
Example:

If a number is multiplied by 1 then the product is the number itself.
Example:

If the number “a” is multiplied by the number “b” then the product is same
as the number “b” multiplied by the number “a”.
Example:
