Algebra is a way of working with numbers and signs to answer a mathematical problem (a question using numbers) As a single word‚ "algebra" can mean[1]: * Use of letters and symbols to represent values and their relations‚ especially for solving equations. This is also called "Elementary algebra". Historically‚ this was the meaning in pure mathematics too‚ like seen in "fundamental theorem of algebra"‚ but not now. * In modern pure mathematics‚ * a major branch of mathematics which
