• How to use it?

• Canonical form:
• x+2y+z,y-z-x+y
• xy+x+y=0
• 4x^2-16y^2-8x+96y-204=0
• 9x^2-36y^2+4z^2-18x+72y+16z-47=0
• Plot:
• x^2/16+y^2/4=1
• abs(x^2-1)+2x-x^2=abs(y^2-1)+2y-y^2
• atan(y)=-atan(x)+3
• y^2=x^2-x^4

• Identical expressions

• x+2y+z,y-z-x+y
• x plus 2y plus z,y minus z minus x plus y
