algebra is the practice of using letters (such as x, y, or z) to represent unknown values in equations. It is a way to solve problems by manipulating these symbols to find the value of the unknowns.

A Tutor for Word Algebra Problems Although the studies described so far have implications for instruction, they do not deal with instruction directly. For this work, we need more than a model of how students comprehend, remember, and learn. We also need, first of all, a theory of instructio...
SageMath provides a variety of algorithms and methods for solving linear algebra problems, such as performing matrix operations, solving linear systems of equations, finding eigenvalues and eigenvectors, and computing matrix decompositions (e.g., LU, QR, SVD). SageMath is a powerful tool for ...
Although I have always been good at math, I use the Algebrator to make sure my algebra homework is correct. I find the software to be very user friendly. Im sure I will be using it when I start college in about one year. H.M., Texas All in all I like the program. Jeff Galligan...
Understanding Pre-Algebra teaches and develops the math concepts and critical thinking skills necessary for success in Algebra I and future mathematics courses at the high school level. It was written with the premise that students cannot problem solve
over them: precedence and containment (alike the set-theoretic approach,Section 3.3) [Becheret al., 1998]. From a model of time units consisting of a finite sequence of rational numbers, the authors build an algebra of relations between these units, obtaining an algebraic account of granularity...
