Algebra
Algebra is a branch of mathematics that deals with the study of mathematical symbols and their manipulation. It uses letters or symbols to represent unknown values in equations or formulas, allowing us to solve problems by finding these values. Algebra is commonly taught in middle and high school and is essential for understanding more advanced math concepts, such as advanced algebra, geometry, and calculus.
Geometry
Geometry is the study of shapes, sizes, positions, and dimensions. It deals with points, lines, angles, surfaces, and solids. Geometry is used in everyday life and is important in fields like architecture, engineering, and construction.
Fractions
Fractions are a way to represent parts of a whole. A fraction is made up of two parts: the numerator (the top number) and the denominator (the bottom number). For example, the fraction (\frac{1}{2}) represents one half of a whole. Fractions can be simplified, converted to decimals, and expressed as percentages.
Decimals
Decimals are a way to represent fractions. A decimal is a number that has a dot (.) after the whole number part. For example, 0.75 is the same as the fraction (\frac{3}{4}). Decimals can be converted to fractions and percentages.
Percentages
Percentages are a way to represent parts of a whole as a percentage of the whole. For example, 50% means half of a whole. Percentages can be converted to fractions and decimals.
Linear Equation in Two Variables
A linear equation in two variables is an equation that can be written in the form (ax + by = c), where (a), (b), and (c) are constants, and (x) and (y) are variables. These equations can be graphed on a coordinate plane and have a unique solution. Linear equations in two variables are used to model real-world situations, such as the relationship between the cost of a product and the quantity sold.
To learn more about these topics, try practicing problems, watching instructional videos, or seeking out additional resources online. Happy studying!
