Algebra on the Digital SAT
Algebra is one of the two largest Math domains, tied with Advanced Math, and it is the foundation everything else builds on. You work with linear equations, systems, functions, and inequalities in one and two variables, and you move between their equations, tables, and graphs.
Because it is over a third of the Math section and the concepts repeat, Algebra is the highest-leverage place to be fast and accurate. Points here are also the most reliable: the setups are familiar, so speed comes from practice, not luck.

Where it appears
Math is not grouped by domain. All four domains are mixed through each module and ordered easiest to hardest, so these questions can appear anywhere. Your total is spread across both modules.
How one Math module is ordered
Based on our analysis of official Bluebook practice tests, Math modules are not grouped by domain: all four domains are mixed across the 22 questions and ordered easiest to hardest, so Algebra questions can appear anywhere in the module.
The 4 skills in Algebra
Each has its own guide: what the SAT tests, the strategies that work, and practice questions with worked solutions.
Linear Equations in One Variable
Master linear equations in one variable for the Digital SAT: solving steps, no-solution and infinite-solution cases, plus practice questions with explanations.
Linear Equations in Two Variables
Beat systems of equations on the Digital SAT: substitution vs. elimination, solution counts, and word-problem setup, with worked practice questions.
Linear Functions
Linear functions on the Digital SAT: slope and intercept meaning, f(x) notation, and building equations from two points, with practice questions.
Linear Inequalities in One or Two Variables
Linear inequalities on the Digital SAT: when to flip the sign, budget and constraint word problems, and practice questions with full explanations.
Desmos for Algebra
Solve these with the built-in calculator
Several Algebra questions are faster on the Digital SAT's Desmos graphing calculator than by hand. Here are the 6 moves that apply to this domain, each with a worked walkthrough.
- 1Solve Any Equation by Graphing
- 2Graph a System of Two Linear Equations
- 3Read a Line's Slope and Intercepts from Its Graph
- 11Graph a System of Inequalities to Test a Point
- 12Use a Slider to Test an Unknown Constant
- 13Find a Constant for the Number of Solutions

How many Algebra questions are on the SAT?
College Board does not publish a fixed count, but Algebra makes up ≈35% · 13–15 questions of the Digital SAT Math section. The exact number shifts slightly from one test form to the next.
Where do Algebra questions appear on the Digital SAT?
Math is not grouped by domain. All four domains are mixed through each module and ordered easiest to hardest, so these questions can appear anywhere. Your total is spread across both modules. The Math section is split into two adaptive modules, and this domain shows up in both.
