WebOct 4, 2009 · 1. Python is dynamically typed, you don't need to declare the type of a variable, because a variable doesn't have a type, only values do. (Any variable can … WebAll we can do with these is simplify or evaluate for given values. Examples could include x, 3x + 2y, etc. Next, we can set two expressions equal to each other by creating an equation. This will allow us to solve or isolate a variable. Examples could be 2x + 5 = 3x - 9 or y = 3x - 2. With two variables, an equation can be a function if each ...

http://www.icoachmath.com/math_dictionary/unknown.html WebTo create a variable, you just assign it a value and then start using it. Assignment is done with a single equals sign ( = ): >>>. >>> n = 300. This is read or interpreted as “ n is assigned the value 300 .”. Once this is done, … An unknown is a variable in an equation which has to be solved for. An indeterminate is a symbol, commonly called variable, that appears in a polynomial or a formal power series. Formally speaking, an indeterminate is not a variable, but a constant in the polynomial ring or the ring of formal power series.
