Too many students feel that they are “bad at math”, and often, educators and experts in the field know the answers but are unable to explain the process of how they arrived at the correct solution.
Pharmaceutical Mathematics was developed with those ideas in mind – to help future pharmacy technicians learn, and to help educators show the steps involved in the process of finding consistent solutions to all pharmacy math questions. This text focuses on building foundational skills, and then surrounding those skills with sound logical processes with minimal memorization so that students can build solutions to any pharmacy math question using critical thinking as their main tool. With a significant focus on math literacy, students can approach pharmacy math with confidence, ease, and the knowledge that they will never again say that they are “bad at math”. Additionally, students will be prepared for the national exam for licensure by covering basic math problems, conversion between various systems of measurement, adult and pediatric dosage calculations and other advanced calculations including: alligations, body surface area, ratio strengths, percentage strengths, dilutions, and IV flow rates.
