#DOES NOT EQUAL SIGN UNICODE PLUS#

Confusingly, some fonts display this symbol with different numbers of 'legs': eight, as a 45°-rotated hash symbol, or six as an asterisk. The projecting lines of the smash product symbol resemble the legs of a spider. Spiders or other bugs found within someone's house or workspace may be caught with a glass and something flat, often a card or a magazine, to be released outside. This is apparently important because the sets can't be isomorphic (one cannot be rearranged to be exactly the other.) That is, if you take the union of any collection of topological spaces in the collection (even uncountably many), or the smash product of them, the result will also be in that collection. Indicates that a collection of topological spaces is closed when taking arbitrary unions and smash products. Rowling.Ĭlosed Union with Serifs and Smash Product The character Larry Potter figured in a fraudulent legal claim against J.K. Harry Potter is known for having a lightning bolt-shaped scar on his forehead. Looks like the letter 'L' and a lightning bolt. GPT-3 has suggested it could indicate particles interacting in physics. Speculation includes a diode with a gate, proof by contradiction, a proofreaders' mark to split a word, and indication of polarization direction. 'Def' is a contraction of 'definitely' used in slang the equal sign looks like a double underline, indicating heavy emphasis. Indicates an equation where the left side is to be defined as the right side usually used in proofs to indicate a definition is being introduced Looks like two squiggles to represent snakes and an arrow indicating the direction where they may be found. Pairs with ⭂ which could conceivably mean assignment of an approximation, but neither seem to be in use. Rightwards Arrow Above Reverse Almost Equal To

Looks like a cup with a plus to indicate adding drink to the cup. May look like a mouth eating an S, where the S symbolizes some snack food.ĭisjoint union (joining a family of sets that have no elements in common) Plural for the angle symbol (∠) rarely used Question marks are commonly used in cartoons to indicate confusion on the part of a character. One metaphor used when teaching inequality signs in primary school is that the sign looks like an alligator mouth 'eating' the larger number. Used in proofs to indicate a greater-than relation that should exist but hasn't been proven yet (non-rigorous) Looks somewhat like the hash symbol (#) – commonly used for indicating tags called hashtags in social media – turned by 45 degrees. The quotient of the underlying spaces of two pointed spaces, where points in the product spaces are identified if they contain either labeled point as an element. Looks like a diagram of a roundabout as might be shown on a minimap beside a routing direction. May look like a shark fin sticking out of the water. No known mathematics use, but resembles the National Park Service cartographic symbol for a campsite.
