Understanding Multiplication: A Key Skill for Competitive Exams

• Multiplication is one of the four basic arithmetic operations, along with addition, subtraction, and division. It is essentially a shortcut for repeated addition. For example, 36 × 12 means adding 36 to itself 12 times (36 + 36 + ... 12 times).

• To solve 36 × 12, you can use the standard long multiplication method or the distributive property.

Methods for Calculation:

• Standard Long Multiplication:

  1. Multiply 36 by the units digit of 12 (which is 2): 36 × 2 = 72.

  2. Multiply 36 by the tens digit of 12 (which is 10): 36 × 10 = 360. (Place a zero in the units column as you are multiplying by 10).

  3. Add the results: 72 + 360 = 432.

• Using the Distributive Property:

  • Break down 12 into (10 + 2): 36 × (10 + 2).

  • Apply the distributive property: (36 × 10) + (36 × 2).

  • Calculate each part: 360 + 72.

  • Add the results: 432.
