return x+y
def subtract(x,y):
return x-y
def multiply(x,y):
return x*y
def divide(x,y):
return x/y
print("Select operation")
print("1.add")

print("3.multiply")
print("4.divide")
while True:

print(num1,"+",num2,"=",add(num1,num2))
elif operation=="2":
print(num1,"-",num2,"=",subtract(num1,num2))
elif operation =="3":
print(num1,"*",num2,"=",multiply(num1,num2))
elif operation=="4":
print(num1,"/",num2,"=",divide(num1,num2))
break

else:
print("Invalid")
