Four problems from each of the eight Algebra Adventures lessons — 32 in all. Every problem is freshly generated, so you can take this as many times as you'd like and never see the exact same set twice. Everything is done right here on screen — no paper or pencil needed.
Work through all 32 problems below. Some ask for a number, some ask you to type a simplified expression, and a couple ask you to graph or plot right on the screen. When you finish the last one, scroll down for your grade and a skill-by-skill breakdown.
