negative numbers are any number less
than zero imagining something less than
zero can be difficult suppose you have a
bowl of oranges and someone takes them
away until you have zero left when
there's nothing it's hard to imagine
being able to take away more however
there are instances in real life where
we use numbers less than zero for
example did you know the average
temperatures at the top of Mount Everest
range from negative 19 degrees Celsius
to negative 36 degrees Celsius wow
that's cold negative numbers also appear
a lot in finances to show debt suppose
you have 50 dollars in your bank account
but then you accidentally spend 60 your
accounts balance is now negative pens
this means you owe the bank 10 dollars
to understand negative numbers even more
let's look at a number line for every
positive number there is a negative
number negative numbers can also be
thought of as the opposite of a positive
number so the opposite of 5 is negative
5 you might also notice that as we go
further down the number line the
negative numbers appear to get larger
however the numbers are really getting
smaller for example negative 10 is
smaller than negative 5 this can be
confusing but think about it in terms of
temperature suppose on a winter's day
it's negative 25 degrees Celsius in
Barrow Alaska and negative 35 degrees
Celsius and family idaho family would be
colder than Barrow because negative 35
is lower than negative 25 now you know
the basics of negative numbers
