You need to complete the code in the following functions:
- SubtractNumbers
- MultiplyNumbers
- DivideNumbers
'''

    This function should return num_1 + num_2.

    '''
    This function should return num_1 - num_2. Replace the line below with the
    correct code.
    '''
    return num_1 - num_2


def MultiplyNumbers(num_1, num_2):
    '''
    This function should return num_1 * num_2. Replace the line below with the
    correct code.

    This function should return num_1 / num_2. If there is a divide by 0 error,
    return the string 'Error'. Repalce the line below with the correct code.
