To simplify the expression, we need to find a common denominator for the fractions. The common denominator for 21, 23, and 177 is 4833.

Now, let's convert each fraction to have the common denominator:

-5/17 * 4833/21 = -2415/357
21/23 * 4833/23 = 21063/529
39/177 * 4833/177 = 106047/3111

Now, we can add the fractions:

-2415/357 + 21063/529 + 106047/3111

To add fractions, we need to have a common denominator. The common denominator for 357, 529, and 3111 is 529 * 3111 = 1643819.

Now, let's convert each fraction to have the common denominator:

-2415/357 * 1643819/357 = -387246285/128013
21063/529 * 1643819/529 = 3486961597/278641
106047/3111 * 1643819/3111 = 5566699933/964221

Now, we can add the fractions:

-387246285/128013 + 3486961597/278641 + 5566699933/964221

To add fractions, we need to have a common denominator. The common denominator for 128013, 278641, and 964221 is 128013 * 278641 * 964221 = 35294720877049153.

Now, let's convert each fraction to have the common denominator:

-387246285/128013 * 35294720877049153/128013 = -49775790701482852605/1643819
3486961597/278641 * 35294720877049153/278641 = 35294720877049153/1
5566699933/964221 * 35294720877049153/964221 = 35294720877049153/1

Now, we can add the fractions:

-49775790701482852605/1643819 + 35294720877049153/1 + 35294720877049153/1

To add fractions, they must have the same denominator. In this case, the denominators are already the same, so we can simply add the numerators:

(-49775790701482852605 + 35294720877049153 + 35294720877049153) / 1643819

Simplifying the numerator:

-49775790701482852605 + 35294720877049153 + 35294720877049153 = -49775790701482852605 + 70589441754098306

= -49775790701482852605 + 70589441754098306

= -49775790701482852605 + 70589441754098306
