Unknown in Mathematics

Unknown refers to something we do not know, which means it is uncertain or unknown. In mathematics, this can refer to situations where you don't have enough information to solve a problem or answer a question. For example, if you want to find out what percentage of students passed an exam without knowing the total number of students who took part, you could say there is an unknown amount left over after removing those who failed from all participants. Another example might involve finding the volume of an object with varying dimensions like a cube; since its sides change continuously due to time passing or external forces acting upon them, any calculated value would only represent one moment in time before continuing to fluctuate again later. Thus, in math, unknown variables often need to be solved through manipulation and estimation based on available data points to make educated guesses about their true values.
