There’s no magic to the letter x - that’s just the most common letter used in Algebra. Understanding a problem and finding the unknown, x, is working with Algebra. Using tricks like writing the problem out with words and flipping things around are just ways to make finding that unknown...

By the way, in the above identities, the angles are denoted by Greek letters. The a-type letter, "α", is called "alpha", which is pronounced "AL-fuh". The b-type letter, "β", is called "beta", which is pronounced "BAY-tuh". ...
What is the meaning of algebra in math? Branches of Mathematics: Mathematics is a very broad subject. Because of this, there are different areas of mathematics, called branches of mathematics. Each of these have different names and cover different topics within the study of mathematics. ...
Numerical variables are the variables you’re most familiar with: numbers. For example, those “x” and “y” variables in algebra stand for a number. Categorical variablesarevariablesthat aren’t numbers: they are descriptive. For example, sex (male or female), occupation, school district, st...
can become somewhat moot if there is a third hypothesis that ends up being more plausible than either of these two hypotheses. Nevertheless, the formula(1)can still lead to useful conclusions, albeit ones that are qualified by the particular assumptions and estimates made in the analysis. ...
What this symbol " ^ " means in a complex fraction such as "3/x^2"? What do the shorthand computer symbols * and / mean in algebra? What do the upside-down question marks indicate in the equation? What is the meaning of the sign "^" in the equation: 2x^2 - 7?
Since these quantities change they are may be called variables. In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation or an algebraic expression. In simple words, a variable is a quantity that can be changed and is not fixed. Variables are ...
In the history of mathematics, the “naive” approach of putting difficulties with precision, formalization or even downright contradictions aside and working with an intuitive understanding has frequently turned out to be quite fruitful. Examples include the initial uses of imaginary numbers in algebra...
There is a 0.25 probability of guessing correctly on a 10 question quiz. What is the probability of getting 5 or more questions correct? What is applied probability and statistics? Is probability and statistics part of algebra? To determine the probability of an event, use the formula P(E) ...
