Zero was invented by ancient civilizations in India a long time ago. Many mathematicians worked over time to develop it into what we use today.

Question 4

How do we use zero in everyday life?

Accepted Answer

We use zero to talk about quantities, like having zero apples if there are none left. It's also used in clocks and thermometers to show exact numbers, like zero degrees.

Question 5

Is zero a big number or a small number?

Accepted Answer

Zero is actually neither big nor small; it is right in the middle. It represents having nothing of something.

Question 6

Can you divide by zero?

What about subtracting zero?

Accepted Answer

Just like adding zero, when you subtract zero from a number, nothing changes. The number remains the same.

Question 10

When zero is divided by any other number, the answer is always zero. It's like having zero pieces of candy and sharing it, everyone still gets zero.

Question 12

Why do we need zero when writing numbers?

Accepted Answer

Zero helps us show the difference between numbers like 10 (ten) and 100 (one hundred). It's a placeholder for empty places in a number.

Question 13

How did people do math before zero was invented?

Accepted Answer

Before zero, people found it hard to do complex calculations. They used different ways, which were often difficult and not very clear.

Question 14

What role does zero play in a number line?

Accepted Answer

On a number line, zero is the center point. Numbers get larger to the right of zero and smaller to the left.

Question 15

Is zero a positive or negative number?

Accepted Answer

Zero is neither positive nor negative; it is neutral. It sits right between positive and negative numbers.

Question 16

How does zero help with big numbers?

Accepted Answer

Zero helps in creating big numbers easily. By adding zeroes, you can multiply numbers and figure out big amounts, like thousands or millions.

Question 17

What happens if you multiply a number by zero?

Accepted Answer

If you multiply any number by zero, the answer is always zero. It shows that having zero groups of any number results in zero.

Question 18

Yes, other ancient cultures like the Maya also used zero, but it took different forms and meanings until modern times.

Question 19

What is the history of zero in the book?

Accepted Answer
