Basics

Calculate things:
13*42*(3+32)/12
The math is parsed and calculated by math.js use it as a syntax reference.
Data is saved when you press GO/Enter
Copy/Paste URL to share sheet
Use backspace to delete an empty cell
Use semicolon (;) to write what you would write on many cells:
a = 1; b=2; sin(a+b)

Numbers

You can use the electrical engineering notation with numbers (n,u,m,k/K,meg/M,G)
ex: 1K = 1000

Functions

You can define functions like that: f(x) = x**2
Then you can use f(x): f(pi)

Constants

pi, e (Euler), i (sqrt(-1)), etc. mathjs constants

Plots

You can plot an expression:
plot("sin(x+0.5)")
plot("e**x")
Plot more than one function at once:
plot("e**x","sin(x)")

Polar plots are also available
pplot("1+sin(theta)")
Default range is [-π, π], to override it:
pplot("theta",0,10)

Fractals

For 10 iterations and a size of 140 pixels:
Julia: zfractal("z**2+0.4-0.05i",10,140)
Mandelbrot: zfractal("z**2+c",10,140)
Cellular automaton: rule(45)

Math

sin(3.14)
sin(360deg)
a = 30
b = 3 * a
b (to show the value of 'b')

Conversions

3 meters to inches
3 in to cm
1 gal to L
1 L to cm^3
4 bytes in bits

Comments exist to let you explain what you are doing.
Create text cells with this syntax:// Comments can be used to describe what's next
Once created, click a comment to edit it.
Use comments at the end the line to describe what you are doing: 1+1 // Here is a simple addition

Bonus

a=1K; b=2K; LL(a,b) : equivalent value of resistors in parallel.
