Topic: Multiplication with larger numbers

Description:

Multiplying larger numbers is an extension of basic multiplication. When you multiply numbers with more than one digit, you follow a process called long multiplication. This involves multiplying each digit of the numbers separately and then adding the results together. The process might seem complex at first, but by breaking it down step by step, it becomes much easier.

To multiply larger numbers:

Examples:

Example 1:
Multiply 23 by 5:
Step 1: Multiply the ones place: 3 × 5 = 15. Write down 5 and carry over 1.
Step 2: Multiply the tens place: 2 × 5 = 10, then add the carry-over (1): 10 + 1 = 11.
Final result: 23 × 5 = 115.

Example 2:
Multiply 47 by 6:
Step 1: Multiply the ones place: 7 × 6 = 42. Write down 2 and carry over 4.
Step 2: Multiply the tens place: 4 × 6 = 24, then add the carry-over (4): 24 + 4 = 28.
Final result: 47 × 6 = 282.

By practicing multiplication with larger numbers, you'll get more comfortable with breaking down the steps and solving even bigger problems. This skill is important in many areas of math and everyday life!
