Money
Now we know that humankind find money useful
when they want to trade things between themselves,
a unit of value that they can agree on.
And it was so useful
that people soon stopped trying to get what they wanted by swapping things
and used money all the time for selling and buying.
But it was not always trading in things that had value.
People would work for money,
doing jobs that other people couldn't do
or didn't want to do.
Someone might chop wood, or cut hair,
or pick crops at harvest time.
People learned to think of the worth of what they had in terms of money,
budgeting to make it last during times that they would not be earning,
like those who might help a farmer pick the crops at harvest time
which only lasts for a short while of the year.
Jobs change with the seasons
and people have times when they are richer or poorer.
Even kids that only have pocket money,
usually given to them for doing very little
except being someone's kids,
know there is only so much you can buy
with a certain amount of money,
and they have to decide what they think is
the most important thing to spend their money on,
what they want most
and what they are prepared to do without for a while
until they can get more money.
So when people are trying to work out what they want to spend their money on
it is good to be able to see what something costs
compared to something else,
and shopkeepers put labels on their things
with the prices they want to charge.
But sometimes they will lower the price of a thing
to try to sell more,
to make something seem cheaper than its real value.
They will have sales at a discount.
But labels can be very confusing,
and lots of shopkeepers will use that fact
to take advantage of those who don't know how to do the maths.
What if a label says 40% off?
First of all it is important to ask 40% off what?
Was it really worth what they say it should be
and would it be worth what it costs now
if they weren't saying it is a bargain?
And supermarkets were made to put labels on their goods
to make it easy to compare the actual costs of similar things,
but they still manage to keep things confusing
by using labels with offers like 3 for 2,
or buy one and get one half price.
They make it so that you need good maths
to be able to work out exactly what you are paying
for what you are getting.
Only with God can you be sure
that you will get your exact worth.
