Can you give five examples of symbol?

Answer 1

* A multiply symbol, e.g. a*b means a multiplied by b. ** An exponentiation symbol, e.g. a**b means a to the power b. + The 'plus' symbol, applicable to the addition operation and simple signage (where it is usually omitted, implicit). , Used in British tradition to punctuate integers, at every third position left-wards from the decimal point, but used in European practice as the decimal point. Consequently abjured within this text in favour of the space character (which is used likewise to punctuate the fractional part). - The 'minus' symbol, applicable to the subtraction operation and simple signage.

. Identically the 'full stop' of British tradition and the 'period' of North America, now universally also the 'dot', but also the 'decimal point' used in English-speaking practice for separating integer and fractional parts of a number, even of a non-decimal number. Used likewise in this text. : The ratio symbol. ∧ Used in emails and some other typographically constrained situations as an exponentiation symbol, e.g. a∧bmeans a to the power b. / Called 'solidus' properly but 'slash' vernacularly, it is used as a ratio or divider symbol, including within the formalities of the SI, e.g. a/b means a divided by b. ˜ The 'tilde' of Spanish orthography; used within this text, in a lowered position, to represent further unstated digits in a number. • Historically the decimal point of British practice, now a multiply symbol, e.g. a·b means a multiplied by b. γ [Etymology: Gk letter 'g', its name Anglicized as gamma]
