This document provides examples of evaluating algebraic expressions by substituting numeric values for variables. It works through examples like finding the value of 5X^2 - 4XY + 3Y^3 if X = 2 and Y = 1. The value is calculated to be 15. Further examples show evaluating expressions like 15a^3 + 2d^2 and 8m^2 + 2n^3 by substituting values for variables a, b, c, d, m, and n.
