I have switched my robot over to Ez-Robot and I need some help converting the following Python script over the EZ-Robot language.

if (data == "lets do some math"): math()

if (data == "one"):
      one()
      global first
      first += 1
      print(first)

if (data == "two"):
      two()
      global first
      first += 2
      print(first)

if (data == "three"):
      three()
      global first
      first += 3
      print(first)

if (data == "four"):
      four()
      global first
      first += 4
      print(first)

if (data == "five"):
      five()
      global first
      first += 5
      print(first)

if (data == "add one"):
      plusone()
      global second
      second += 1
      print(second)

if (data == "add two"):
      plustwo()
      global second
      second += 2
      print(second)

if (data == "add three"):
      plusthree()
      global second
      second += 3
      print(second)

if (data == "add four"):
      plusfour()
      global second
      second += 4
      print(second)

if (data == "add five"):
      plusfive()
      global second
      second += 5
      print(second)

if (data == "what does that equal"):
      equals()
      global number
      number = (first+second)
      i01.mouth.speak(str(first) + "plus" + str(second) + "is" + str(number))
      global first
      first = (first + second)
      global second
      second = 0

if (data == "start over"):
      i01.mouth.speak("OK")
      rest()
      sleep(2)
      i01.mouth.speak("ready")
      global first
      first = 0
      global second
      second = 0
      print("starting from 0")

It's a script where the robot does addition. Can anyone help me out with this, thanks
