Example 1: In modular arithmetic: If two integers a a and b b leave the same remainder when divided by an integer n n, we can say a ≡ b a ≡ b (mod n n). This denotes that a a and b b are identical with respect to modulo n n. Example 2: In logical equivalences: If two logical statements P P and Q Q are always true at the same time and always ...
The one about "defined to be equal" is often rendered as ":=". I haven't seen " ≡ " used for that. It's certainly used for congruence with respect to a modulus; e.g. 44 ≡ 62 (mod 6), etc. It's used for identities like (x + 1)2 = x2 + 2x + 1 when one wants to say that that is true for all values of x. However, the variety of different uses ...
Without proper rendering support, you may see question marks, boxes, or other symbols. The triple bar or tribar, ≡, is a symbol with multiple, context-dependent meanings indicating equivalence of two different things. Its main uses are in mathematics and logic. It has the appearance of an equals sign = with a third line.
Symbol Symbol Name Meaning / definition Example; x: x variable: unknown value to find: when 2x = 4, then x = 2: ≡: equivalence: identical to : ≜: equal by definition: equal by definition := equal by definition: equal by definition ~ approximately equal: weak approximation: 11 ~ 10: ≈: approximately equal: approximation: sin(0.01) ≈ 0.01 ...
The $\equiv$ symbol originally meant "is identically equal to", and as that name implies it is used with identities. It is actually stating that the equality holds for all instantiations of the free variables.
Mar 23, 2012 · The symbol ≡ is used to indicate equivalence or congruence between two objects, while the equal sign (=) is used to denote equality or sameness between two values. Additionally, the symbol ≡ is often used in specific mathematical or logical contexts, while the equal sign (=) is more commonly used in general equations. 4.

Apr 24, 2024 · (mathematics) "Is identically equal to". The functions f and g satisfy f≡g if and only if their respective domain of definition coincide, and if f(x)=g(x) for all x in this domain. (mathematics) "Is defined as, is set to". (number theory) "Is congruent to"; used in calculations of modulo.
