Preface

This is an inline calculator, each calculation will be calculated line by line.

You can store values in variables to use on other lines.

How to use it?

1 + 1 will return 2

Operator Function
+ Add
- Subtract
* Multiply
/ Divide
^ Power
sqrt(n) Square Root

To see more possible operations, to go mathjs operators documentation.

Comments

If you want to create a comment, just use the # sign, everything after the # will be ignored.

Variables

You can assign variables to use later.

pizzas = 2

pizzaPrice = 30

people = 4

(pizzas * pizzaPrice) / people will return 15

Function Variables

To store a function in a variable, just type:

myCustomFunction = f(x) = x * 2

The body of the function can be whatever you want.

To use a function, type:

myCustomFunction(4) will return 8

Unit conversion

You can convert some units.

1cm to m will return 0.01 m
