Pi isn’t just for math—it shows up in nature, too. You can find it in circles like the sun, the spiral (螺旋) of DNA and the eye’s pupil (瞳孔). We can also find pi in the rivers.Every year on March 14, students celebrate Pi Day by enjoying pies. Can you guess why?
What does ^ mean in mathematics? What do the shorthand computer symbols * and / mean in algebra? What this symbol " ^ " means in a complex fraction such as "3/x^2"? In math, what does the word 'of' mean? What does 2^3 mean? What does that symbol stand for?
For example, 1 + 8 + 27 + ... + 1000 can be written using sigma notation as ∑10i=1∑i=110 i3, as the elements are the cubes of natural numbers from 1 to 10. How Do You Find Sigma in Math? To find the sigma in math, we either expand it and find the sum manually or we...

There are many different symbols that arise in discrete math. The symbol of particular interest and discussion in this lesson is called the empty set. In mathematics, a set is a collection of unique objects. The notation for a set is: {eq}S= \lbrace ... \rbrace {/eq} where the eleme...
We shall use “not-A” or “¬A” as abbreviations for the statement that “statement A is not true;” some mathematicians use other symbols such as ∼ A. The symbol ¬, meaning “not,” is also called negation. In conventional (ordinary) logic, used throughout most of this book...
In such a case, the postulates of the theory will exhaustively describe the stock of permissible texts. The syntactics for programming languages has been so well developed that there are even means of machine verification to check whether programs have been correctly devised. In the case of ...
Expected value or expectation of a random variable $X$ is defined, if it exists, in a mathematically precise way with respect to a probability space, typically denoted as $(\Omega, \mathcal{A}, \mathbb{P})$, where $\Omega$ is the universe of possibilitie
