# IB Maths Studies SL Review Notes

Simple IB Maths Studies SL review notes with what symbols mean, when to use triangle equations, calculator work for TI-84(+) (Texas Instruments), logic definitions, etc.

It mainly consists of symbols that need to be memorised, a couple equations that are not in the booklet, and also how to achieve some answers from the calculator (specific to the TI-84 only).

Maths Studies is not a priority for most people, so I took the liberty to create this simple guide that hopefully will help you on your IB Exams for Maths.

I am a student, not a teacher.

If there are any suggestions to add to this general review, or someone would like a step-by-step for a topic under Maths Studies SL they do not understand, please message me.
