print(" 1 for add")
print(" 2 for subtract")
print(" 3 for multiply")
print(" 4 for divide")
choice = input("select the number you want for operation")
x = int(input("first number for operation"))
n = int(input("second number for operation"))
if choice == 1:
print(int(x) + int(n))
if choice == 2:
print(x - n )
if choice == 3:
print(x * n)
if choice == 4:
print(x / n)
