Algebra is a branch of mathematics that helps to show relationships. A common algebra application is calculating how the supply of an object (x) relates to the price of that object (y). If the price of an object decreases by a scale of 2, then the algebraic formula, or mathematical statement, to express this idea would be x = y -- 2.
Algebra is similar to the scientific method, which tries to find an outcome or explanation to events and variables. Often, algebra is a tool used in science experiments, such as measuring units and variables in astronomy. With prior knowledge of the scientific method, students can better understand how to use algebra effectively in problem-solving situations.
In algebra, a person can calculate the probability of events using linear graphs, such as an xy axis. On this axis, a mathematician can apply an x- and a y-coordinate to show how the variables are related. The graph can show how one of the variables increases or decreases in relation to the other. This activity examines if there are causal relationships between numbers, an activity that can postulate a hypothesis, be tested on a linear graph, and affirm a mathematical theory. The scientific method thus helps students see how algebra calculates relationships and causality.
Many natural and social science fields apply algebra in the scientific method to ascertain a more complete explanation of events. For example, economists utilize algebra to test hypotheses about the market. Chemists need to know algebra so they can calculate the effects of certain mixtures. Builders need an understanding of algebra to calculate the dimensions of a home or other structure.
