# Everyday Maths

### Did you know?

Time, as we count it today, started in ancient Babylon and is based on their mathematics. Their system of counting was based on the number 60 in the same way as we base our counting on the number 10. This is why there are 60 seconds in a minute and 60 minutes in an hour.

The Babylonians had a system to write symbols to represent the numbers between 1 and 59 which is much like many other system of early civilisations. When they reached 60 they simply started over with the symbol for 1. The only difference, it was in the next column over.

### False Economy

A term you might have heard is ‘false economy’. This is something, like a deal or special offer, that seems to save you money, but when you look closer (and apply a bit of maths) it actually doesn’t.

Example: you are in the supermarket and you see an offer for 3 jars of coffee for £5. This is right next to other jars of the same coffee that are £3 each. If you like coffee there is no question right? – 3 for £5 it is.

But wait, if we look closer we see that the coffee in the deal is in 150g jars, whereas the coffee not in the deal is in a 400g jar. So the ‘deal’ is (3×150) 450 grams for £5 as opposed to 400 grams for £3. The extra 50 grams in the deal is hardly worth the extra money so this deal is a false economy.

Sneaky offers like this are all over the supermarket and everywhere else. It is not to say that everything on offer is bad, but being able to spot the dodgy ones will save you money.
