print(10 + 20)                  # 30
print(20 - 10)                  # 10
print(10 * 20)                  # 200
print(20 / 10)                  # 2

# power
print(10 ** 2)
# 100

# floating point conversion
print(10.0 + (10 + 20))         # 40.0
print(20.0 - (10 + 10))         # 0.0
print(10.0 * (10 * 2))          # 200.0

# common division error
print(30 / 20)                  # 1
print(30.0 / 20.0)              # 1.5

# integer divison, quotient
print(20.0 // 20.0)             # 1.0
print(30.0 // 20.0)             # 1.0
print(40.0 // 20.0)             # 2.0

# modulo, remainder
print(12.5 % 10.0)              # 2.5
print(10.0 % 20.0)              # 10.0

# built-ins
