In the expression 5 - (m/n) - 2 - 8(m + n), we can describe the different parts using the following terms:
1.) Factor: The expression (m/n) can be described as a factor of the first term, 5 - (m/n).
2.) Product: The expression 8(m + n) can be described as a product of 8 and the sum (m + n).
3.) Quotient: The expression (m/n) can also be described as a quotient of m divided by n.
4.) Sum: The expression (m + n) can be described as a sum of the variables m and n.
5.) Difference: The expression 5 - (m/n) - 2 can be described as a difference between the first term (5 - (m/n)) and the constant 2.
