What is it?

A 'number fact' for a number like 14 is simply a pair of numbers that add up to 14. These are like mini-addition problems where the answer is always 14. Knowing these facts helps you add and subtract faster in your head.

Simple Example

Quick Example

Imagine you have 14 laddoos. If you eat 10 laddoos, you are left with 4. So, 10 and 4 make 14. This means '10 + 4 = 14' is a number fact for 14. Similarly, if you have 7 red roses and 7 yellow roses, you have 14 roses in total, so '7 + 7 = 14' is also a number fact for 14.

Worked Example

Step-by-Step

Let's find all the number facts for 14, starting from 0.

Step 1: Start with 0. What number do you add to 0 to get 14? It's 14. So, 0 + 14 = 14.
---
Step 2: Next, try 1. What number do you add to 1 to get 14? It's 13. So, 1 + 13 = 14.
---
Step 3: Try 2. What number do you add to 2 to get 14? It's 12. So, 2 + 12 = 14.
-----
Step 4: Continue this pattern: 3 + 11 = 14, 4 + 10 = 14, 5 + 9 = 14, 6 + 8 = 14.
---
Step 5: When you reach 7, you get 7 + 7 = 14. If you go further, like 8 + 6 = 14, it's just the reverse of 6 + 8 = 14. So, we usually stop when the numbers start repeating or reversing.
---
Answer: The number facts for 14 are: (0, 14), (1, 13), (2, 12), (3, 11), (4, 10), (5, 9), (6, 8), and (7, 7).

Why It Matters

Understanding number facts builds a strong foundation for all maths. It helps you do calculations quickly in your head without needing a calculator. This skill is vital for careers like becoming a data analyst, an engineer designing bridges, or even managing a small business where you need to calculate costs and profits fast.

Common Mistakes

MISTAKE: Only thinking of one way to make 14, like just 7 + 7. | CORRECTION: Remember there are many pairs of numbers that add up to 14. Systematically find all pairs, starting from 0.

MISTAKE: Confusing number facts with multiplication facts (e.g., thinking 2 x 7 = 14 is a number fact). | CORRECTION: Number facts specifically refer to pairs of numbers that ADD up to the target number, not multiply.

MISTAKE: Forgetting that 0 can be part of a number fact (e.g., ignoring 0 + 14 = 14). | CORRECTION: Always start finding number facts from 0 to make sure you don't miss any pairs.

Practice Questions

Try It Yourself

QUESTION: Which of these pairs is NOT a number fact for 14: (5, 9) or (6, 7)? | ANSWER: (6, 7) is not a number fact for 14 because 6 + 7 = 13, not 14.

QUESTION: If you have 14 rupees and spend 8 rupees on a samosa, how much money do you have left? What number fact does this show? | ANSWER: You have 6 rupees left (14 - 8 = 6). This shows the number fact (8, 6) because 8 + 6 = 14.

QUESTION: Find two different number facts for 14 where both numbers in the pair are even. | ANSWER: (4, 10) because 4 + 10 = 14, and (6, 8) because 6 + 8 = 14.

MCQ

Quick Quiz

Which of the following is a number fact for 14?

14 - 0 = 14

7 x 2 = 14

14 + 0 = 14

5 + 9 = 14

The Correct Answer Is:

A number fact is about two numbers adding up to the target number. Option D, 5 + 9 = 14, correctly shows two numbers adding up to 14. Options A and C are subtraction/addition involving 0, but not showing a 'pair' that makes 14 in the usual sense of number facts, and B is a multiplication fact.

Real World Connection

In the Real World

When a shopkeeper in India calculates your change after you buy something, they quickly use number facts. For example, if your bill is 6 rupees and you give 10 rupees, they know that 6 + 4 = 10, so they give you 4 rupees back. Similarly, when estimating how many passengers can fit in an auto-rickshaw based on how many are already inside, you use number facts.
