Heart of Algebra, on repeat: linear equations, systems, inequalities, and word problems, an endless pool of questions, free.
Unlimited Practice, FREE →No sign-up required · Instant feedback · New questions every time
Every question is generated fresh, so you never run out and never end up memorizing answers. Submit and instantly see whether you're right, with a worked solution for every problem. Then filter by difficulty, from Easy to Expert, to stay right at the edge of what you're learning. No account, no paywall, no limit. It's completely free.
Algebra is the single biggest content domain on the digital SAT math section, and it’s built almost entirely out of a handful of question shapes: solve for a variable, read a linear function off a graph, translate a word problem into an equation, work a system or an inequality. Once those shapes feel automatic, the section gets a lot less stressful.
That kind of automatic recognition only comes from seeing the same idea dressed up differently, over and over. Score800Math’s Algebra practice generates a new version of each question type every time, at a difficulty you pick, so you’re never just re-memorizing one specific problem.
Linear equations and word problems, reading linear functions off graphs, systems of equations, linear inequalities, and general algebraic manipulation, the "Heart of Algebra" domain of the digital SAT.
