have distinct ways of conceptualizing the respective knowledge bases. Mathematical knowledge for teaching is viewed as a practice-based knowledge base, defined in terms of its use in performing specific tasks of mathematics teaching. Mathematics didactic knowledge, on the other hand, is seen as a th...
The definition of an expression in math is a statement composed of terms and operations. The terms may be constant (numbers), or variables with coefficients. The operations may be addition, subtraction, multiplication, or division. Does a math expression have an answer? Arithmetic expressions have...
Terms like “sum,”“difference,”“product,” and “quotient” are not merely labels; they represent the very building blocks of numerical manipulation. Beyond the elementary operations lie more advanced concepts, such as prime numbers and composite numbers, terms that classify inte...

Slide rules are pointless for addition and subtraction, but there is more to the gimbal calculations than that. John Llewellyn was the real life slide rule guy, and he claims that he did use a slide rule for such calculations. Are You With It? (1948) IMDB *** Donald O'Connor plays ...
Mathematical properties are extensively used in different fields involving mathematics since the rest of the calculations will depend on how the terms on both sides of the equation are related to each other. For instance, in Chemistry, there are several cases in which distributive property...
For instance, Peirce's project of understanding better our modes of mathematical reasoning in logical terms can be taken to be a part of the same general project. At first sight, this shift of perspective nevertheless does not seem to matter very much to the problem of logicism. Set theory...
A mathematical expression consists of terms—objects themselves consisting of zero, one, or several variables, potentially raised to a power, and a coefficient, joined by multiplication—joined by addition and subtraction, and factors—components of expressions connected by multiplication that can be sim...
arithmetic: the part of mathematics that studies quantity, especially as the result of combining numbers (as opposed to variables) using the traditional operations of addition, subtraction, multiplication and division (the more advanced manipulation of numbers is usually known as number theory)....
