Is 70 odd or even

Step by step

The question

Question: is 70 odd or even?

Even means it makes pairs, with none left over.

Odd means one is left over.

1 Look at the ones

70 is 70 and 0.

Every ten makes 5 pairs.

So 70 is all pairs.

Only the 0 ones are left to check.

2 Put the ones in pairs

There are 0 ones.

Nothing is left over.

3 Odd or even

None left over.

So 70 is even.

4 Check

We count by 2s from 70: 70.

We land on 70.

Yes!

It works.

Let's look back.

First: look at the ones.

Then: put the ones in pairs.

Then: odd or even.

Last: check.
