Which is the correct way to use the equals sign?
Symbols used to denote items that are approximately equal include the following: ≈ (U +2248, LaTeX approx) ≃ (U+2243, LaTeX simeq), a combination of ≈ and =, also used to indicate asymptotic equality ≅ (U+2245, LaTeX cong), another combination of ≈ and =, which is also sometimes used to indicate isomorphism or congruence
Which is the best description of typesetting of text?
For broader coverage of this topic, see Typography. Typesetting is the composition of text by means of arranging physical type or its digital equivalents. Stored letters and other symbols (called sorts in mechanical systems and glyphs in digital systems) are retrieved and ordered according to a language’s orthography for visual display.
