## The Beauty of Odd Factors

Remember that the factors of an odd number are all odd.

For example the factors of 15 are: 1, 3, 5 and 15.

If we look at a bigger number like 2,469 the factors are: 1, 3, 823, 2469.

And just to prove the point, for a huge number like 24,648,021 the factors are: 1, 3, 9, 53, 159, 477, 51673, 155019, 465057, 2738669, 8216007, 24648021.

Phew!

## How long will it take me to walk 6km?

A Ninja Maths Master should be able to estimate how long a walk will take

The average ten year old child will walk at about 4km per hour.

With this knowledge a Ninja Maths Master should be able to work out that 6km is one and a half times 4km, so the time taken will be one and a half times one hour which is one and a half hours!

Ask how long it would take to walk 40km. The answer will not be ten hours. Why?
