A well-known equality featuring the equal sign. The equals sign (British English) or equal sign (American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense. [1]
U+2252 ≒ APPROXIMATELY EQUAL TO OR THE IMAGE OF: Which is used like "≈" or "≃" in Japan, Taiwan, and Korea. U+2253 ≓ IMAGE OF OR APPROXIMATELY EQUAL TO: A reversed variation of U+2252 ≒ APPROXIMATELY EQUAL TO OR THE IMAGE OF. U+225F ≟ QUESTIONED EQUAL TO: U+2A85 ⪅ LESS-THAN OR APPROXIMATE: U+2A86 ⪆ GREATER-THAN OR APPROXIMATE
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
33 is the 21st composite number, and 8th distinct semiprime (third of the form where is a higher prime). [1] It is one of two numbers to have an aliquot sum of 15 = 3 × 5 — the other being the square of 4 — and part of the aliquot sequence of 9 = 3 2 in the aliquot tree (33, 15, 9, 4, 3, 2, 1).
1. Means "less than or equal to". That is, whatever A and B are, A ≤ B is equivalent to A < B or A = B. 2. Between two groups, may mean that the first one is a subgroup of the second one. ≥ 1. Means "greater than or equal to". That is, whatever A and B are, A ≥ B is equivalent to A > B or A = B. 2.
Mathematics: There are approximately 1.869 × 10 4099 distinguishable permutations of the world's largest Rubik's Cube (33×33×33). Computing: 1.189 731 495 357 231 765 05 × 10 4932 is approximately equal to the largest value that can be represented in the IEEE 80-bit x86 extended precision floating-point format.
A wavy equals sign (≈, approximately equal to) is sometimes used to indicate rounding of exact numbers, e.g. 9.98 ≈ 10. This sign was introduced by Alfred George Greenhill in 1892. [1] Ideal characteristics of rounding methods include: Rounding should be done by a function
e, approximately equal to 2.718281828459045235360287. [9] i, the imaginary unit such that i 2 = −1. [10] (square root of 2), the length of the diagonal of a square with unit sides, approximately equal to 1.414213562373095048801688. [11]
