Algebra is a type of math where we use letters and symbols to represent numbers and equations. We use algebra to solve problems that involve variables, formulas, and equations. For example, we might use algebra to figure out how much money we will have after saving $10 each week for a certain number of weeks, or to find out how many hours we need to work to reach a certain goal. Algebra is important for many areas of science, engineering, and business, and it can also help us understand patterns and relationships in the world around us.
