Adding and subtracting algebraic fractions is a similar process to adding and subtracting normal fractions. The denominators of each fraction are different, \(3t\) and \(7t\), so a common denominator ...

Students of Grade 7 were given a test followed by individual interviews; at the end of Grade 8 the same students were subject to an analogous test and interviews. Each student had to simplify certain ...

Algebraic logic constitutes a vibrant interdisciplinary field that investigates the close interplay between algebraic structures and logical systems. By utilising tools from universal algebra, ...
