It works great on your phone - full screen if you add it to your homescreen.

#### Example in C :

Calculate (3+2i)*(1+4i)

- C
- (3+2 e1)
- *
- (1+4 e1)
- =
- answer is -5+14e1

#### Example in D

Calculate the value of the function and first derivative at x=3
f(x)=x3-2x2+3

- D
- 3+e0
- ST x1
- Cl x1*x1*x1-2*x1*x1+3
- =
- answer is f(3)=12 and f'(3)=15

#### Example in spacetime M

You see two simultaneous lightning strikes in 10 microseconds, one where you are, one 20 km in the x-direction.
Are these events simultaneous for a spaceship flying at 0.5c in the x-direction? (given : atanh(0.5)=0.5493)

- M
- 0.0 0 0 0 1 e1
- ST x1
- +2 0 e2/3 0 0 0 0 0
- ST x2
- Cl(0.5 4 9 3*.5 e1 e2)Exp
- ST x3
- Cl x3*x1*x3 x̄
- ST x4
- Cl x3*x2*x3 x̄
- ST x5
- answer is strikes happen at (X4 : 11ms) and (x5 : -26ms) - not the same time.

#### Example in PGA 2D (2,0,1)

Solve the system of equations :

- x+y-0.5=0
- 2x-1y=0
  - P2D
  - e1+e2-0.5 e0
  - ST x1
  - Cl 2 e1-e2
  - ST x2
  - Cl x1∧x2
  - ST x3
  - Cl x3/(-E0●x3)
  - =
  - answer is x=0.166666 and y=0.3333333
