Arithmetic and Fraction Step Check
Check a supplied arithmetic equality chain exactly, locate its first value error and offer a focused hint.
How to use it
Tell your assistant what you want to check and provide the relevant records. It will ask only for the facts that change the result and organize the data for you.
Check a supplied arithmetic equality chain exactly, locate its first value error and offer a focused hint.
Try saying
Check my child’s written fraction steps and give a hint at the first error before showing the answer.
Are these decimal and fraction expressions exactly equal? Keep the work my child actually wrote.
What you receive
A readable review report and detailed records showing the supplied facts, issues and unknowns. The original files stay intact. Only the supplied arithmetic chain is checked. Hints identify the first value difference without inventing unseen work.
Runs locally with Python 3.10+ standard library; no paid data key or backend account needed. Optional explanation uses your current agent model and normal service charges separately. It does not create automatic tasks, notifications or account actions.
