UnicodeMath resembles real mathematical notation the most in comparison to all of the math linear formats, and it is the most concise linear format, though some may prefer editing in the LaTeX input over UnicodeMath since that is widely used in academia. The math environment is for formulas that appear right in the text. Basic Code Special keys. This also means that, of course, if "\hline" is used in mid-paragraph, then it will force a break in. This command does not seem to be well documented but appears to work, at least in current versions of LaTeX 2. Summation notation is often known as sigma notation because it uses the Greek capital letter sigma, $\sum$, to represent the sum. The math environment is for formulas that appear right in the text. The number on top of the summation sign tells you the last number to plug into the given expression. This happens so often that we turn it into a rule, and a very useful piece of shorthand: “if we appear to be multiplying two terms containing the same suﬃx, then actually we sum those terms over.$ We now discuss how to obtain integrals in mathematical documents. To see an equation heavy paper on an elementary topic (accessible to undergraduates), check out Finite Summation of Integer Powers (Part 3). The style and size of the fraction will depend on whether the command is used inline with text or in display format.
