SINGLE-LINE IF STATEMENT EXAMPLE fruit = "apple" IF fruit == "apple" PRINT "Fruit does equal apple!" PRINT "This prints regardless of fruits value."

END PRINT "This prints regardless of fruits value."

ASK EXAMPLE name = ASK "Enter your name: " PRINT "Welcome to Route, " PRINT name

>MATH OPERATORS Math operations are written in the form "variable sign= parameter" where the parameter will be applied to the variable using the sign.

MATH EXAMPLE number = 10 number += 1 PRINT number number -= 1 PRINT number number *= 2 PRINT number number /= 2 PRINT number
