Mathematics
The same algebra, calculus, and proof work the STEM programme actually assigns, not a generic math tutor.
Egyptian STEM mathematics is a sequence, not a pile of worksheets. Limits sit next to the algebra you already proved. Differentiation sits next to the functions your grade actually uses. My Learning opens that course in the same order your school mapped it, lesson by lesson, with the notes attached to each row.
When you ask from a lesson, the assistant searches those notes. A derivation that is not on the page does not get invented. You get the steps that are there, or a plain I could not find this in your materials.
Sigma sits on the chat rail while you work. That is company, a character from the product, not a certificate and not proof that the answer is right. The citation is the proof. Open the note and check the line.
Start on My Learning, open your math course, and keep the question inside that lesson. The map and the assistant stay on the same materials.
Try asking: walk the chain rule from my differentiation lesson notes, and show the line you used.
