Algebra is the branch of mathematics that uses numbers, letters and signs to generalize the various arithmetic operations / algebraic structures. The term comes from the Latin algĕbra which derives from an Arabic term meaning "reduction". Algebra occupies an essential place between arithmetic and geometry making it possible to extend and unify the numerical domain. You can find extended structure of Algebra such as linear and multilinear algebras and topological algebra
In mathematics, a fraction shows how a whole is divided up. A simple fraction represents an integer numerator displayed above a line, and a non-zero integer denominator, displayed below that line. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. Fractions are interesting as there are many ways of utilization. You can use fractions in your daily lives to represent ratios and division
The word trigonometry is derived from two Greek words which means triangle and measurement. Trigonometry is a branch of mathematics which deals with the relationships between distances and angles in triangles. You can also find trigonometric functions such as sine, cosine and tangent. Trigonometry now is used in many different areas such as science and engineering. The trigonometry studies measurement in a two-dimensional plane as in a three-dimensional space. Consequently, trigonometry has been divided in two broad types : plane trigonometry and spherical trigonometry
