1.What is Multiplication?

Multiplication is the process of adding a number to itself a certain number of times. It’s a shortcut for repeated addition. For example, 3×4 means adding 3 four  times: 3+3+3+3 =12.

Key Terms:

1.    Multiplicand: The number being multiplied (e.g., in 5×6, 5 is the multiplicand).

2.    Multiplier: The number by which the multiplicand is multiplied (e.g., in 5×6, 6 is the multiplier).

3.    Product: The result of multiplication (e.g., in 5×6=30, 30 is the product).




 

2.Properties of Multiplication

Understanding the properties of multiplication can make calculations easier:

1.    Commutative Propertya×b=b×a (e.g., 3×4=4×3).

2.    Associative Property(a×b)×c=a×(b×c) (e.g., (2×3)×4=2×(3×4).

3.    Distributive Propertya×(b+c)=(a×b)+(a×c)  (e.g., 2×(3+4)=(2×3)+(2×4).

4.    Identity Propertya×1=a (e.g., 7×1=7).

5.    Zero Propertya×0=0 (e.g., 9×0=0).

 Easy Multiplication Tricks




1. Multiplying by 10, 100, or 1000

  • To multiply a number by 10, add a zero at the end (e.g., 24×10=240).
  • To multiply by 100, add two zeros (e.g., 24×100=2400).
  • To multiply by 1000, add three zeros (e.g., 24×1000=24000).

2. Multiplying by 5

  • Multiply the number by 10 and then divide by 2.
  • Example: 16×5=(16×10)÷2=160÷2=80.

3. Multiplying by 9

  • Multiply the number by 10 and then subtract the original number.
  • Example: 12×9=(12×10)−12=120−12=108.


3.Vedic Math Tricks for Two-Digit and Three-Digit Multiplication

Vedic math, an ancient Indian system, offers quick and efficient methods for multiplication. Here are two popular techniques:

1. Nikhilam Sutra (Base Method)

This method is useful when numbers are close to a base (like 10, 100, 1000).

Example: Multiply 98 × 97

  • Step 1: Find the difference between each number and the base (100):
    • 98−100=−2
    • 97−100=−3
  • Step 2: Add the differences to the numbers diagonally:
    • 98+(−3)=95 or 97+(−2)=95
  • Step 3: Multiply the differences:
    • (−2)×(−3)=6
  • Step 4: Combine the results:
    • 98×97=9506

2. Urdhva-Tiryagbhyam Sutra (Vertically and Crosswise)

This method works for any two-digit or three-digit numbers.

Example: Multiply 23 × 41

  • Step 1: Multiply the digits vertically:
    • 3×1=3 (last digit)
  • Step 2: Multiply crosswise and add:
    • (2×1)+(3×4)=2+12=14 (middle digit)
  • Step 3: Multiply the first digits:
    • 2×4=8 (first digit)
  • Step 4: Combine the results:
    • 23×41 =943

Practical Examples

Example 1: Two-Digit Multiplication

Multiply 34×12:

  • 34×10 =340
  • 34×2 =68
  • Add: 340+68 =408

Example 2: Three-Digit Multiplication

Multiply 123×45:

  • 123×40 =4920
  • 123×5 =615
  • Add: 4920+615 =5535

 What is Division?



Division is splitting a number into equal parts or groups. It’s the opposite of multiplication.


Key Terms in Division:

1.    Dividend – The number being divided (e.g., in 15 ÷ 3, 15 is the dividend).

2.    Divisor – The number we divide by (e.g., in 15 ÷ 3, 3 is the divisor).

3.    Quotient – The answer (e.g., 15 ÷ 3 = 5, so 5 is the quotient).

4.    Remainder – The leftover amount if the division isn’t exact (e.g., 16 ÷ 3 = 5 with 1 left over).


Easy Division Tricks & Methods

1. Repeated Subtraction Trick

Instead of dividing directly, subtract the divisor repeatedly until you reach zero or a remainder.

Example: 20 ÷ 4

  • 20 – 4 = 16
  • 16 – 4 = 12
  • 12 – 4 = 8
  • 8 – 4 = 4
  • 4 – 4 = 0
    Total subtractions = 5 → So, 20 ÷ 4 = 5

2. Multiplication Backwards

Since division is the opposite of multiplication, think of a multiplication fact.

Example: 42 ÷ 6 = ?
Think: 6 × ? = 42 → 6 × 7 = 42 → So, 42 ÷ 6 = 7

3. Break It Down (Partial Division)

Split the dividend into smaller, easier-to-divide numbers.

Example: 72 ÷ 6

  • Break 72 into 60 + 12
  • 60 ÷ 6 = 10
  • 12 ÷ 6 = 2
  • Add them: 10 + 2 = 12 → So, 72 ÷ 6 = 12

4. The "Halfway" Trick for Dividing by 5

To divide by 5, multiply by 2 and then divide by 10 (or move the decimal).

Example: 45 ÷ 5

  • 45 × 2 = 90
  • 90 ÷ 10 = 9 → So, 45 ÷ 5 = 9

5. Long Division Made Simple (DMAS Rule)

Use Divide, Multiply, Subtract, Bring Down, Repeat (DMSBR):

Example: 126 ÷ 3

1.    Divide: 3 into 1? No → Take 12 → 3 goes into 12 4 times.

2.    Multiply: 4 × 3 = 12

3.    Subtract: 12 – 12 = 0

4.    Bring Down: 6 → Now divide 6 by 3 → 2

5.    Answer: 42

 

Fun Story Sums (Word Problems)

1. Sharing Pizza

Riya has 18 slices of pizza and wants to share them equally among 6 friends. How many slices does each get?
Solution: 18 ÷ 6 = 3 slices each

2. Books on Shelves

A library has 45 books to place equally on 5 shelves. How many books per shelf?
Solution: 45 ÷ 5 = 9 books per shelf

3. Remainder Scenario

Sam has 23 candies and packs them into boxes of 5. How many full boxes can he make, and how many candies are left?
Solution: 23 ÷ 5 = 4 boxes with 3 candies left (remainder).

 

Engaging Division Activities

1. Division Bingo

  • Create bingo cards with division problems (e.g., 16 ÷ 4, 27 ÷ 9).
  • Call out quotients, and players mark matching problems.

2. Real-Life Grouping

  • Use beads, coins, or Legos to physically divide into groups.
  • Example: Divide 20 Legos into 4 towers. How many in each?

3. Flashcards & Apps

  • Use flashcards for quick practice.
  • Try math apps like Prodigy or Khan Academy Kids for interactive learning.
