# Key points

- Numbers can be integers, such as $2$, or floats (decimals), such as $7.8$,
although JavaScript doesn’t differentiate between them and just has a
single primitive data type of `Number`.

- Numbers can be written in exponential notation, such as `5e6` for five
million.

- The arithmetic operations +, -, *, / and % can be applied to any two
numbers.

- It’s possible to change strings to numbers and vice versa.

- If we try to perform operations between a string and a number, JavaScript
will attempt to convert the type to complete the operation. This can cause
some inconsistent and unexpected results!

- A random number between $0$ and $1$ is returned by the `Math.random()`
method.

After the quiz and challenge, we'll look at how
JavaScript deals with collections of values.
