Mar 2, 2018 · Where implicit multiplication is appropriate, in algebraic expressions, between a number and a symbol, or between two symbols, neither $:$ not $\div$ should be used to express division. Rather division should be shown using a horizontal line. This means there is no confusion possible between $$\frac{a}{b}\left(c+d\right)$$ and $$\frac{a}{b(c+d)}$$
Only infix notation requires the additional symbols. The order of operations within prefix and postfix expressions is completely determined by the position of the operator and nothing else. In many ways, this makes infix the least desirable notation to use.

Let’s first look at one of the earlier questions we had about this issue, in 1999, to set the stage: (Note that at that time, the only way to type division in our email was to use the slash, a/b, which I generally assume represents an expression actually written as a÷b. I will occasionally be inserting an obelus, ÷, where we made rough attempts to ...
Here is a typical example of a school conflict, from 2000: The problem is N÷ml, and the parents are doing the multiplication first. I replied, in part: I explained the standard rules, and added: I’ll have more on the history next time. More recently, the fights tend to be on social media!
I’ll close with the most recent archived discussion. This question is from 2017: I answered with a collection of my standard answers to this sort of question; even my first archived answer on the topic in 1999 was largely a standard response I had given to others before. Here, I’ll just look at a few points I made that haven’t been fully covered ab...
Miscellanea. v. t. e. In mathematics, matrix calculus is a specialized notation for doing multivariable calculus, especially over spaces of matrices. It collects the various partial derivatives of a single function with respect to many variables, and/or of a multivariate function with respect to a single variable, into vectors and matrices that ...
Feb 5, 2024 · The Alphabet of Mathematics. Today’s mathematical notation is a rich tapestry of symbols. It includes: Numbers and Operations: The most basic elements, including numbers, and fundamental operations like addition (+), subtraction (-), multiplication (× or ·), and division (÷ or /). Algebraic Symbols: Variables (like x, y, z) represent ...
Mathematical notation is a system of symbolic representations used for mathematical objects, operations, relations, and concepts. Here are some of the most commonly used notations: {} : Set notation. Example: {1, 2, 3} is the set containing 1, 2, and 3. ∈ : Element of.

Feb 24, 2020 · The first service that the notation for zero has rendered, as Whitehead says, has been “to make the Arabic notation possible – no slight service” (Whitehead 2017, 36). For, by serving as a placeholder in the Arabic or decimal notation, it has made possible to write all numbers, no matter how big or small, using ten symbols alone.
