To evaluate an algebraic expression, just plug numbers into the expression and simplify it.
Don't Forget: you will need your faithful friend PEMDAS (aka Order of Operations).
Evaluate the expression when x = 2, y = 3, and z = 1. 
Find the values of the expression for x = 2, 1, 0, 1, 2 This question is asking us to evaluate the expression for five different values. It may be easiest to do this in chart form.

Which of these values (2, 1, 0, 1, 2) makes this equation true? Just like the previous problem, it is probably useful to make a chart. 
Evaluate the expression 3x^{2} + 5xy – 2 for x = 3 and y = 2.
The formula for the surface area of a cone is πrs + πr^{2}, where r is the radius of the base and s is the length of the slant. Find the surface area of a cone with radius 10 cm and a slant of 12 cm (use 3.14 for π).
Evaluate the expression x^{3} + x^{2} + x + 1 for x values equal to 2, 1, 0, 1, 2.
Which of these values of x (1, 2, 3, 4, 5, 6) make this equation true: x^{2} – 8x = 12?
