Tip for parents and teachers
Draw a quick sketch and write every given value WITH its sign before you substitute. Most marks in numericals are lost on signs, not on arithmetic.
How to use this formula sheet
Print it and keep it on the study table or inside the notebook cover. Cover the right-hand side and test yourself before exams.
Printing tip: choose A4 and “fit to page” in your print settings. Black-and-white printing works fine — the drawings are simple outlines that are light on ink. You are welcome to print as many copies as you need for your own children or your class; please share the link to this page rather than the file.
