Mathematics is the study of topics such as quantity, structure, space, and change. Mathematicians seek patterns and use them to formulate conjectures, which they then aim to prove or disprove through mathematical proof. When mathematical structures accurately model real phenomena, mathematics can provide insight and predictions about nature. Mathematics has developed through concepts like counting, calculation, measurement, and the study of shapes and motions, and is used throughout the world as an essential tool across many fields like science, engineering, medicine, and finance.
