How Do You Know? Let's Try With Math can be used as a main text for preparatory courses or as a supplement to a core textbook in survey and general chemistry courses. Many students needing help apart from the classroom in chemistry may find How Do You Know? Let's Try With Math, useful as a self-paced learning guide. How Do You Know? Let's Try With Math, take a look at chemistry and mathematics. Its purpose is to teach students the basic concepts of chemistry and problem solving techniques. Teachers and Students need not have a science background or extensive math skills to use this curriculum. Most calculations in chemistry involve only simply algebra. There are two basic approaches for solving these equations. The first is the use of the factor-label method to convert information from one set of units into another. Second is the use of a memorized equation or law into which data for all variables except one are inserted. The one remaining variable is the unknown for the problem. Correct use of the second approach also requires that all unites be shown to ensure that they cancel properly to yield the desired units for the numerical answer.
Scientific calculators simplify mathematical operations to the touch of a few keys. Understanding the principles and concepts of chemistry enables us to decide in which order to press those keys. Understanding numbers tells us how to properly interpret the answer that appears on the calculator screen. See (Data Analysis and Statistical Approach to the Equation of Line)
