Don’t worry, math does not need to be your strong-suit to learn JavaScript. There are just a few operations we’ll need to know to make some awesome programs later in the course!).

JavaScript includes the general math operators that you can find on a calculator:

1. Add: `+`
2. Subtract: `-`
3. Multiply: `*`
4. Divide: `/`

These all work how you might guess: `3 + 4` will equal `7`, `50 / 10` will equal `5`.

Let’s use each one of these math operators.

### Instructions

1.

Inside of a `console.log`, add `3.5` to your age.

This is the age you’ll be when we start sending people to live on Mars.

2.

On a new line write another `console.log`. Inside the new `console.log`‘s parentheses, take the current year and subtract `1969`.

The answer is how many years it’s been since the 1969 moon landing.

3.

Create another `console.log`, then divide `65` by `240`.

4.

Create one last `console.log`, then multiply the full answer from step 3 by `100`.

That’s the percent of the sun that is made up of helium. Assuming we could stand on the sun, we’d all sound like chipmunks!
