num1 = input('First Number: ')
num2 = input('Second Number: ')
op = input('Operator: ')
try:
num1 = int(num1)
num2 = int(num2)
except:
print('Input a valid number!')
continue
if op not in ['+', '-', '*']:
print('Invalid operator!')
continue
if op == '+':
print(str(num1 + num2))
elif op == '-':
print(str(num1 - num2))
elif op == '*':
print(str(num1 * num2))
