#Task 1: Basic mathematical operations

a=int(input('a:')) b=int(input('b:'))

addition = a+b subtraction = a-b multiplication = a*b division = a/b

print('addition =',addition) print('subtraction =',subtraction) print('multiplication =',multiplication) print('division =',division)

#Task 2: Personalized greeting

a= input('enter your first name:') b= input('enter your last name:')

print("Hello"+","+" ", a + b +"!"+ " Welcome to the Python program.")
