Simple Example

Quick Example

Imagine you buy 2 packets of biscuits. Each packet has 12 biscuits. To find the total number of biscuits, you would calculate 2 × 12. You are essentially counting 12 biscuits, then another 12 biscuits.

Worked Example

Step-by-Step

Let's calculate 2 × 12:
1. We need to multiply 2 by 12.
---
2. One way to think about this is adding 12 to itself two times: 12 + 12.
---
3. Start with the ones place: 2 + 2 = 4.
---
4. Now add the tens place: 1 + 1 = 2.
---
5. Put them together to get 24.
---
6. So, 2 × 12 = 24.

Why It Matters

Understanding basic multiplication like 2 × 12 is super important for higher Maths, computing, and even AI! In computing, knowing how to multiply helps you understand how computers process data and perform calculations very fast. Future careers in data science or software development rely on these foundational skills.

Common Mistakes

MISTAKE: Thinking 2 × 12 is the same as 2 + 12. | CORRECTION: Multiplication means repeated addition (12 + 12), not just adding the two numbers together.

MISTAKE: Multiplying 2 by only the '2' in 12, ignoring the '1' (tens place). | CORRECTION: Remember to multiply the 2 by both the ones digit (2) and the tens digit (1) of 12, or use repeated addition.

MISTAKE: Confusing the multiplication symbol '×' with the addition symbol '+'. | CORRECTION: The '×' symbol always means multiply, which is a faster way to add the same number multiple times.
