Each panel below is a working miniature of a site that could run at this address: navigation, hero, product screen and proof numbers, followed by a plain note on how that business would position the name. All twenty stay on screen at all times; a lane simply marks its own. The domain sits in the browser bar of every one of them, whole and unbroken, because the name is the thing being sold.

MathSolver is a declared type in the shared vocabulary that search engines read. It descends from CreativeWork, it carries a mathExpression property, and it has a companion action for solving. The name of this domain is the name of the type.

The answer is
the least of it.
A solver that returns 4 has told a student nothing. A solver that names the operation on every line has handed them a worked example, which is one of the better-evidenced things you can put in front of somebody learning algebra.

A photograph of a handwritten equation, a typed string, a spoken sentence. Each one has to become the same structured thing before a single operation runs. The parse is the part nobody sees and the part that is hardest to get right.

Check the work
Not wrong. Wrong
starting here.
A student submits five lines of working. Four of them are right. Marking the whole thing incorrect teaches nothing; marking line three teaches the thing they actually need. Checking your own work is the use that every academic integrity policy we read explicitly permits.

Six years running,
then once more.
Federal law requires mathematics to be assessed in each of grades three through eight and at least once in high school. Science is required three times in a student's entire career. Reading and math are the two subjects the country measures annually, by statute.

The subsidy expired.
The schools kept going.
States spent close to a billion dollars of federal relief money on tutoring in a single fiscal year, and three thousand districts stood up intensive programs. Every obligation and liquidation deadline for that money has now passed. As of mid-2025, forty-two percent of public schools still ran high-dosage tutoring.

An intervention that cannot show growth against a comparison band will not survive a second budget cycle. The strongest evidence in this space comes from homework systems that gave students feedback and hints while they worked, and it cleared the federal evidence standard without reservations.
