Multiply 2-Digit by 2-Digit | Multiplication:- Easy Step-by-step Guide | By mudassir sir

Multiplication of 2-digit numbers by 2-digit numbers is a fundamental concept in arithmetic operations. Here's a step-by-step description:

Step 1: Multiply the Numbers
To multiply two 2-digit numbers, start by multiplying the numbers as if they were whole numbers.

Step 2: Break Down the Numbers
Break down the numbers into tens and ones. For example, if we are multiplying 43 by 27, break down 43 into 40 + 3 and 27 into 20 + 7.

Step 3: Multiply the Parts
Multiply each part of one number by each part of the other number.

Multiply the Tens
Multiply the tens place of one number by the tens place of the other number. In our example, multiply 40 by 20.

Multiply the Tens by Ones
Multiply the tens place of one number by the ones place of the other number. In our example, multiply 40 by 7 and 3 by 20.

Multiply the Ones
Multiply the ones place of one number by the ones place of the other number. In our example, multiply 3 by 7.

Step 4: Add Up the Partial Products
Add up the partial products from the previous step to get the final product.

Step 5: Write the Final Product
Write the final product as the result of the multiplication.

Example
To multiply 43 by 27:

1. Break down the numbers: 43 = 40 + 3 and 27 = 20 + 7.
2. Multiply the parts:
40 * 20 = 800
40 * 7 = 280
3 * 20 = 60
3 * 7 = 21
3. Add up the partial products: 800 + 280 + 60 + 21 = 1161.
4. Write the final product: 43 * 27 = 1161.

By following these steps, you can multiply any two 2-digit numbers.
