When did you first start using an abacus?

You probably used it when you were in school or college.

But if you didn’t, you probably still use it for some work today.

Now, the word ‘abacus’ has become synonymous with all kinds of things that you don’t normally associate with an object.

But, it was actually invented in 1723 by Johann Georg Bernoulli, a French chemist.

Bernoulli made the first modern abacus in 1730, and by 1750, it had become a universal symbol.

This is where the word came from.

So why do we still use the word abacus for a modern, mass-produced, multi-coloured object that costs almost twice as much as it does today?

The answer lies in the fact that people have always been very familiar with a number of different colours.

There are no standards in the world to distinguish one colour from another.

So the colour black is the same as any other black.

The same is true for red.

It’s just different.

In fact, people are so familiar with colours that they may even go back a few decades and find an object that they use.

For instance, I used to get a lot of questions from my daughter about which of her dolls she used to buy as a baby.

And I’d ask her about the colour blue.

I’d say: ‘Well, I never really used blue, but she used blue because that was the colour I was used to.

So I like it.’

Nowadays, this is all changed.

In the early days, if you bought a doll that had a blue face, you were going to have to spend a lot more money to get it.

But, today, most people buy a blue toy, and it’s only a matter of time before you buy a red one.

And it’s all a matter a few clicks away.

This is the first part of a four-part series on the origins of the wordabacus.

Part two will look at the origins and meanings of the term.
