number = 0 # Set number to 0.
print number

number = number + 10 # number is now 10.
print number

number = number - 3 # number is now 7.
print number

number = number * 3 # number is now 21.
print number

number = number / 7 # number is now 3.
print number

number = number // 2 # number is now 1.
print number

number = number % 2 # number is now 1.
print number

number = 0
number = (((((number + 10) - 3) * 3) / 7) // 2) % 2 # number is now 1.
print number

number = 0
number = number + 10 - 3 * 3 / 7 // 2 % 2 # number is now 10.
print number

number = number ** 2 # number is now 100.
print number
