Math Playground

A multi-line scratchpad: define variables and functions, then build on earlier lines with live results as you type.

Worksheet

One expression per line. Use name = value for variables, f(x) = … for functions and # for comments. Results update as you type.

About the Math Playground

A scratchpad for experimenting. Write one expression per line; define variables and your own functions and reuse them on later lines. Every line is re-evaluated as you type, so you can change a value at the top and watch everything below update.

Matrices, complex numbers and all the functions of the scientific calculator are available.

Limitations

Worksheets are limited to 200 lines and are not saved between visits.
log(x) is base 10 and ln(x) is natural, as in the scientific calculator. Trigonometric functions use radians.

How to use it

Type expressions, one per line.
Assign with =, for example a = 3 or f(x) = x^2 + a.
Read each line’s value in the results panel.

Example

r = 2.5 then pi * r^2

→ 19.6349540849
