Solve Basic Multiplication: 0 × 20 Step by Step

Q: Why does anything times zero equal zero?

Think of multiplication as repeated addition! When you have $ 0 \times 20 $, you're adding 20 together zero times, which gives you nothing (zero).

Q: Is 0 × 20 the same as 20 × 0?

Yes! The commutative property means multiplication works both ways. Whether it's 0 × 20 or 20 × 0, the answer is always zero.

Q: What if the number is really big, like 0 × 1000?

It doesn't matter how big the number is! $ 0 \times 1000 = 0 $, $ 0 \times 1,000,000 = 0 $. The zero property works for any number.

Q: How can I remember this rule?

Think of it as groups: 0 × 20 means zero groups of 20 items. If you have no groups, you have no items total!

Q: Does this work with fractions and decimals too?

Absolutely! $ 0 \times 3.5 = 0 $ and $ 0 \times \frac{1}{2} = 0 $. The zero property applies to all types of numbers.

Understand the problem

$0\times20=$

Step-by-step solution

To solve this problem, we need to multiply $0$ by $20$ . By applying the fundamental rule of multiplication involving zero, we know that any number multiplied by zero is zero.

Therefore, the calculation follows this simple property:

$0 \times 20 = 0$

In the context of a multiple-choice question, we compare our solution with the available options. The correct answer, based on our calculation, is choice :

. Thus, choice 2 is the correct option.

Hence, the final answer to the problem is $0$ .

Final Answer

Key Points to Remember

Essential concepts to master this topic

Zero Property: Any number multiplied by zero always equals zero
Technique: Apply zero rule directly: $0 \times 20 = 0$
Check: Verify using addition: $0 + 0 + 0...\text{(20 times)} = 0$ ✓

Common Mistakes

Avoid these frequent errors

Thinking zero times any number equals that number
Don't think 0 × 20 = 20! This confuses multiplication with addition. Zero groups of 20 items means no items at all. Always remember: zero times anything is zero.
