# Do you know in a computer program a variable can hold different values? 
# In Python a variable can hold different values at different times. 
# Let us take a look
'''******Task 1:Task 1: Variable Challenge*****'''

# Do a mental calculation and tell me what the value of the variables first, second and third:
# first = 2
# second = 3
# third = first * second
# second = third - first
# first = first + second + third
# third = second * first
# Uncomment the statements and click on Run

'''******Task 2: The ‘x’ challenge*****'''
# What do you think is the value of x after these commands execute? 
# Can you do a mental calculation and tell me
# x = 10          
# x = x + x
# x = x - 5
# x = (x*5)/5 + 10
# Uncomment the statements and click on Run
