Powered by MetaNumber

The MetaNumber probe-value engine automatically determines the dimensional signature of any mathematical expression. When a professor enters a formula, the system verifies it is dimensionally correct before any student sees it. When a student submits an answer, the system checks both the value and the dimensional consistency.
