0 times table common mistakes
Likely errors in the 0 times table and gentle ways to fix them using models and reasoning.
Quick answer
Any number multiplied by zero always equals zero. This is the rule for the 0 times table, and it's a special rule that helps us understand how multiplication works.Learning outcome
By the end of this page, you will understand why any number multiplied by zero always equals zero, and you will be able to use this rule confidently in your maths. Success signs:- You can explain that 0 × 5 = 0
- You can solve 0 × 12 = ? without counting
- You can show that 0 × any number = 0 using objects or drawings
- You can explain why this is true using equal groups
Why this matters
Knowing the 0 times table helps you understand how multiplication works. It's a special rule that makes maths more predictable and easier to solve. You'll use this rule in bigger maths problems, and it's also helpful when you're sharing things, like dividing up snacks or toys.How it works
Multiplication is about making equal groups. When we multiply by zero, we make zero groups. So, if you have 5 apples and you make 0 groups, you have 0 apples in total. No groups = no apples. Let's look at how this works:- Think of multiplication as making groups
- When you multiply by zero, you make zero groups
- Zero groups mean zero items
- So, 0 × any number = 0
Examples you can see
Here are some examples to help you understand:| Number | Multiplied by 0 | Answer |
|---|---|---|
| 0 | 0 × 0 | 0 |
| 1 | 0 × 1 | 0 |
| 2 | 0 × 2 | 0 |
| 3 | 0 × 3 | 0 |
| 4 | 0 × 4 | 0 |
| 5 | 0 × 5 | 0 |
| 6 | 0 × 6 | 0 |
| 7 | 0 × 7 | 0 |
| 8 | 0 × 8 | 0 |
| 9 | 0 × 9 | 0 |
| 10 | 0 × 10 | 0 |
| 11 | 0 × 11 | 0 |
| 12 | 0 × 12 | 0 |
- You have 3 toy cars and you want to make 0 groups of them. How many cars do you have? Zero!
- You have 10 stickers and you want to make 0 groups. How many stickers are in the groups? Zero!
- You have 7 balloons and you want to make 0 groups. How many balloons are there? Zero!
Try it as a mini adventure
Imagine you're a space explorer on a mission to collect stars. You find 5 stars, but you can only take 0 stars back to your spaceship. How many stars do you bring back? Zero stars! Now, you find 8 more stars, but still only take 0 back. How many stars are you bringing back now? Zero stars again! Let's try another one:- First time: 0 stars × 12 stars = ?
- Second time: 0 stars × 4 stars = ?
- Third time: 0 stars × 10 stars = ?
- Fourth time: 0 stars × 1 star = ?
Common mistakes
Here are some mistakes children often make when learning the 0 times table:Mistake 1: Thinking 0 × 5 = 5
Incorrect idea: Some children think that when you multiply by zero, you just get the number you started with.
Why it happens: This confusion can happen because children are used to adding numbers, and 0 + 5 = 5. They mix up addition and multiplication.
Correct idea: When you multiply by zero, you make zero groups. So, 0 × 5 means 0 groups of 5 items, which equals 0.
Mistake 2: Thinking 0 × 0 = 0 but 0 × 1 = 1
Incorrect idea: Some children think that 0 × 1 = 1 because they see the 1 in the problem.
Why it happens: This mistake often comes from not understanding that multiplication by zero means no groups, no matter what number you start with.
Correct idea: No matter what number you multiply by zero, you get zero because you're making zero groups of that number.
Mistake 3: Forgetting that 0 × any number = 0
Incorrect idea: Some children remember that 0 × 0 = 0, but forget that 0 × 12 = 0 too.
Why it happens: This can happen because children focus on the bigger numbers and forget the rule.
Correct idea: The rule is always the same: zero groups of any number equals zero.
Mistake 4: Thinking that 0 × 0 = 1
Incorrect idea: Some children think that 0 × 0 = 1 because 0 + 0 = 0 and 0 × 0 = 0, so maybe 0 × 0 = 1.
Why it happens: This is a mix-up between addition and multiplication. Children may confuse the operations.
Correct idea: 0 × 0 means zero groups of zero items, which is still zero. The rule is always the same: zero times anything is zero.
Parent and carer guide
As a parent or carer, you can help your child understand the 0 times table by:
- Using real-life examples like sharing toys or snacks
- Repeating the rule: "Zero groups of any number = zero"
- Using visual aids like drawing groups of objects
- Practising with flashcards or games
- Reassuring your child that it's okay to make mistakes
Here are some things to say:
- "Think of it like this: if you have 0 bags, and each bag has 5 apples, how many apples do you have? Zero!"
- "Zero times anything is always zero. It's like saying 'I have no groups of anything'."
- "Try drawing 0 groups of 3 stars. How many stars do you have? Zero stars!"
What not to worry about:
- Your child might get confused at first – that's normal
- They might make mistakes – that's how they learn
- Don't rush them through the concept

FAQ
Why does 0 times anything equal 0?
Because multiplication is about making equal groups. When you multiply by zero, you make zero groups. So, no matter how many items are in each group, you still have zero items in total.
Is 0 × 0 = 0?
Yes! Zero groups of zero items is still zero. This is the same rule as any number times zero.
Can I use the 0 times table in real life?
Yes! When you're sharing things and you have zero groups, you have zero items. For example, if you have 0 bags and each bag has 5 cookies, you have 0 cookies.
What happens if I divide by zero?
That's a special case in maths that's not covered in the 0 times table. Dividing by zero is not allowed in maths because it doesn't make sense.
How can I remember the 0 times table?
Remember: "Zero groups of anything = zero." You can also think of it like this: if you have no groups, you have no items. No matter how many items are in each group, if there are no groups, you still have zero items.
