Syntax

These syntax guidelines are to be followed-

• Functions: Every function calls must use parentheses for arguments such that a function call will be similar to -> function(arguments)

  Valid syntax: simplify(sin(x) = Log(x) + 2), addition(cos(2) + sin(2))
  Invalid syntax: simplify(sinx = Logx + 2), addition(cos2 + sin3)

• Each open parenthesis must have a corresponding close parenthesis and for a new pair of parenthesis, close parenthesis must never be encountered before the open parenthesis.

  Valid syntax: simplify(x^2 + 2*(x+3) + 5 = (x + 4))
  Invalid syntax: simplify(x^2 + 2*(x+3 + 5 = (x + 4))
  
  Valid syntax: addition(2 + 3 + 4/(2+2))
  Invalid syntax: addition(2 + 3) + 4/)2+2(

• Always use operators for operation between two expression

  Valid syntax: simplify(4 = (x+y)*(x-y))
  Invalid syntax: simplify(4 = (x+y)(x-y))

• Decimal point must be preceded by an integer

  Valid syntax: simplify(0.2*2 + 0.5)
  Invalid syntax: simplify(.2*2 + 0.5), simplify(0.2*2 + .5) or simplify(.2*2 + .5)
