*Make sure you understand the following before moving on:*

- What is an expression in JavaScript?
- How can we access the JavaScript console?

`NaN`

?

Complete the following exercises to practice arithmetic in JavaScript. If you are with a pair, switch off between every section (i.e.: "Add", "Subtract", etc.) or between every prompt (e.g.: "77 to 99", "99 from 665").

- 77 to 99
- 34 to 1233
- -53 to 99

- 99 from 665
- 555 from 23
- 6,348,709,234 from 87,023,984,709,871,234

- 89 and 54
- 932 and 1,900
- -34 and 8

- 1008 by 7
- 9,870,834,205,987 by 324
