Unicode: 2245. Alias: Esc ~== Esc. Infix similarity operator. x ≅ y is by default interpreted as TildeFullEqual[x,y]. Used in mathematics to indicate isomorphism, congruence ...

Unicode: 2248. Alias: Esc ~~ Esc. Infix similarity operator. x ≈ y is by default interpreted as TildeTilde[x,y]. Used for various notions of approximate or asymptotic ...

x < y yields True if x is determined to be less than y. x_1 < x_2 < x_3 yields True if the x_i form a strictly increasing sequence.

With <<, you can read files that contain Mathematica expressions given in input form. Sometimes, however, you may instead need to read files of data in other formats. For ...

Patterns stand for classes of expressions. They contain pattern objects that represent sets of possible expressions. Pattern objects. When several pattern objects with the ...

The general principle that Mathematica follows in evaluating expressions is to go on applying transformation rules until the expressions no longer change. This means, for ...
