  2. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    If exponentiation is indicated by stacked symbols using superscript notation, the usual rule is to work from the top down: [2] [7] a b c = a (b c), which typically is not equal to (a b) c. This convention is useful because there is a property of exponentiation that (a b) c = a bc, so it's unnecessary to use serial exponentiation for this.

    Gram's rule and Rosser's rule both say that in some sense zeros do not stray too far from their expected positions. The distance of a zero from its expected position is controlled by the function S defined above, which grows extremely slowly: its average value is of the order of (log log T ) 1/2 , which only reaches 2 for T around 10 24 .

    In mathematics, an algebraic expression is an expression built up from constants (usually, algebraic numbers) variables, and the basic algebraic operations: addition (+), subtraction (-), multiplication (×), division (÷), whole number powers, and roots (fractional powers).

  7. Elementary algebra - Wikipedia

    en.wikipedia.org/wiki/Elementary_algebra

    [1] Elementary algebra, also known as high school algebra or college algebra, [2] encompasses the basic concepts of algebra. It is often contrasted with arithmetic : arithmetic deals with specified numbers , [ 3 ] whilst algebra introduces variables (quantities without fixed values).

    Calculator Applications is one of several academic events sanctioned by the University Interscholastic League (UIL) in Texas, US. It is also a competition held by the Texas Math and Science Coaches Association, using the same rules as the UIL. Calculator Applications is designed to test students' abilities to use general calculator functions.

  9. Composition of relations - Wikipedia

    en.wikipedia.org/wiki/Composition_of_relations

    Juxtaposition is commonly used in algebra to signify multiplication, so too, it can signify relative multiplication. Further with the circle notation, subscripts may be used. Some authors [ 11 ] prefer to write ∘ l {\displaystyle \circ _{l}} and ∘ r {\displaystyle \circ _{r}} explicitly when necessary, depending whether the left or the ...
