import meth
# tokenizing equations
meth.tokenize("5 + 2") # INT(5), PLUS, INT(2)
# parsing equations
meth.parse("2 * 10") # BinaryOpNode(INT(2), MUL, INT(10))
# evaluating equations
meth.evaluate("2 + 2") # 4
meth.evaluate("sqrt(9)") # 3
# evaluation with variables
evaluator = meth.Evaluator()
evaluator.evaluate("x = 5")
evaluator.evaluate("x") # 5
