How it teaches
By hand first, so you always see the maths. Then the same question in Desmos, the graphing calculator built into the Digital SAT®.
A star marks the questions where Desmos is the quicker way. Where it is not, the solution says so, and Desmos becomes a check.
Every Desmos picture is a real screenshot, made with Desmos.
Every answer is checked by computer. Each question carries its own separate solution, and the site is not published unless every answer matches it.
