## Your number is up! A quick quiz

By

,

This quiz is for all you maths wizards. Can you maximise your score, or does this quiz have your number?

### #1. Is 0 even or odd?

When you divide 0 by 2, you get no remainder. That means 0 is even!

### #2. What is 111,111,111 x 111,111,111?

111,111,111 x 111,111,111 = 12,345,678,987,654,321

### #3. True or false? The company Google was named after a very big number.

True! Google was named after the number googol, which is a 1 with 100 zeros.

### #4. When we write numbers like 12 and 493, we’re using Hindu–Arabic numerals. Where were these numerals invented?

Hindu–Arabic numerals were invented in India and spread westwards through Arabia to Europe.

### #5. Which 2 numbers, multiplied together, make 111?

3 x 37 = 111. You can tell that 111 is divisible by 3 because 1 plus 1 plus 1 is also divisible by 3.

## Results

Congratulations! You are a real science whiz!

Oh dear! Better brush up before the next quiz!

When you divide 0 by pi you get no remainder too, but that doesn’t mean that pi is a factor of 0

Hi MC,
I’m pretty happy to agree that every positive whole number is a factor of 0. Pi can’t be a factor of 0 because factors are always positive whole numbers. Otherwise, a half would be a factor of every integer.

Hi David,

If every positive whole number is a factor of 0, that would seem to invalidate division by 2 as being a test of whether 0 is even.

As division by any positive whole number leaves no remainder, 0 is either “more even” than say, 6, or it’s neither even nor odd. I go with the latter.
