Definition
What is it?
3 x 4 means adding the number 3, four times. It is a basic multiplication problem that helps us find the total when we have equal groups.
Simple Example
Quick Example
Imagine you have 3 laddus, and your friend also has 3 laddus. If two more friends join, and each of them also has 3 laddus, how many laddus do you all have together? You have 4 groups of 3 laddus each. So, 3 x 4 means 3 + 3 + 3 + 3.
Worked Example
Step-by-Step
Let's find the value of 3 x 4.
---Step 1: Understand what '3 x 4' means. It means adding the number 3, four times.
---Step 2: Write out the repeated addition: 3 + 3 + 3 + 3.
---Step 3: Add the first two numbers: 3 + 3 = 6.
---Step 4: Add the next number to the result: 6 + 3 = 9.
---Step 5: Add the last number: 9 + 3 = 12.
---Answer: So, 3 x 4 = 12.
Why It Matters
Understanding multiplication is key for many fields. In Computing, it helps calculate data speeds or memory. AI uses it in complex algorithms for facial recognition. Engineers use it to design buildings and bridges. Learning this skill early helps you build a strong foundation for future studies and careers.
Common Mistakes
MISTAKE: Thinking 3 x 4 means adding 4, three times. | CORRECTION: 3 x 4 means adding the first number (3) the number of times shown by the second number (4). So, 3 + 3 + 3 + 3.
MISTAKE: Confusing multiplication with addition and simply adding 3 and 4 to get 7. | CORRECTION: Multiplication is repeated addition. 3 x 4 is not 3 + 4. It is 3 added 4 times.
MISTAKE: Forgetting the basic multiplication tables and guessing the answer. | CORRECTION: Practice your multiplication tables (like the table of 3 or 4) to quickly recall answers for basic problems like 3 x 4.
