Worksheet for practicing multiplication of negative numbers with questions and interactive links.

Let's solve Question 1 and Question 2 step by step, focusing on the rules of multiplying negative numbers.

---

🔹 Rules for Multiplication with Negative Numbers:

1. Positive × Positive = Positive
Example: $ 3 \times 4 = 12 $

2. Negative × Positive = Negative
Example: $ -3 \times 4 = -12 $

3. Positive × Negative = Negative
Example: $ 3 \times -4 = -12 $

4. Negative × Negative = Positive
Example: $ -3 \times -4 = 12 $

> 💡 Remember: Same signs → Positive, Different signs → Negative

$ = -52 $

(u) $ -11 \times 10 $
→ Negative × Positive = Negative
$ = -110 $

(v) $ -20 \times -6 $
→ Negative × Negative = Positive
$ = 120 $

(w) $ 14 \times 7 $
→ Positive × Positive = Positive
$ = 98 $

(x) $ -18 \times -13 $
→ Negative × Negative = Positive
$ = 234 $

## ✔ Question 2: Multiply three numbers

We can do this step by step using the same sign rules.

---

(a) $ 2 \times 3 \times -2 $
Step 1: $ 2 \times 3 = 6 $
Step 2: $ 6 \times -2 = -12 $
→ Final answer: -12

(b) $ -3 \times 2 \times 5 $
Step 1: $ -3 \times 2 = -6 $
Step 2: $ -6 \times 5 = -30 $
→ Final answer: -30

(c) $ -5 \times -6 \times 2 $
Step 1: $ -5 \times -6 = 30 $ (negative × negative = positive)
Step 2: $ 30 \times 2 = 60 $
→ Final answer: 60

(d) $ 10 \times -3 \times -4 $
Step 1: $ 10 \times -3 = -30 $
Step 2: $ -30 \times -4 = 120 $ (negative × negative = positive)
→ Final answer: 120

📌 Final Notes:

- Always multiply two numbers at a time.
- Keep track of signs carefully.
- The number of negative signs determines the final sign:
- Even number of negatives → Positive
- Odd number of negatives → Negative

For example:
- In (c): two negatives → even → positive
- In (d): two negatives → even → positive
