Download or read book Demystifying the Calculator written by Vinny Madera and published by Independently Published. This book was released on 2020-10-10 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: 7 points. Understanding how to use the functions already built-in to your TI-84 CE calculator can be worth as many as seven extra points on the ACT math section. Sadly, many students do not know how to do much more than add, subtract, multiply, divide, and occasionally graph on their calculators. Since many schools do not have a "set" calculator, many teachers do not teach students to really unlock the true potential of their calculator. This short guide explains the calculator functions that many students would never find unless they were really, really bored in class and exploring the strange buttons they hardly ever press. The author explains the concepts in a clear, easy-to-follow, and humorous way while providing additional practice for students to hone their skills. Additionally, the guide provides students with the questions on recent, released ACTs that can be attacked with the methods provided within. Besides skyrocketing ACT scores, the functions in the guide can be used on SATs, PSATs, or academic math classes.
