I used to hate Math so much when I was in school but ever since the pandemic hit and plus my daughter loves numbers and words so I grew a love for Math now. Life is Math. Everywhere we go there is Math. Science is Math. Many of the problems of science involve an equation, a shorthand way of describing patterns and relationships that are observed in nature.
Equations are also used to identify properties and to define certain concepts, but all uses have well-established meanings, symbols that are used by convention, and allowed mathematical operations. This appendix will assist you in better understanding equations and the reasoning that goes with the manipulation of equations in problem-solving activities.
In addition to a knowledge of rules for carrying out mathematical operations, an understanding of certain quantitative ideas and concepts can be very helpful when working with equations. Among these helpful concepts are (1) the meaning of inverse and reciprocal, (2) the concept of a ratio, and (3) fractions.
SYMBOLS AND OPERATIONS
The use of symbols seems to cause confusion for some students because it seems different from their ordinary experiences with arithmetic. The rules are the same for symbols as they are for numbers, but you cannot do the operations with the symbols until you know what values they represent. The operation signs such as +, ÷, ×, and − are used with symbols to indicate the operation that you would do if you knew the values. Some of the mathematical operations are indicated in several ways. For example, a × b, a · b, and ab all indicate the same thing, that a is to be multiplied by b. Likewise, a ÷ b, a/b, and a × 1/b all indicate that a is to be divided by b. Since it is not possible to carry out the operations on symbols alone, they are called indicated operations. ⁰
