We have already seen how JavaScript can do math.
We can add and subtract any number of numbers together:
1 + 2 + 17 - 9 + 5 - 4
And we get 12
as a result.
Negative Numbers
What happens when you subtract 2
from 1
?
You get -1
, of course. JavaScript knows this. JavaScript understands negative numbers and is happy to work with them as well.
Try running: 1 - 2
Try running: -1 + 2
Try running: -2 + -3
Try running: 1 - -2
