  • Complex conjugate - Wikipedia
    Geometric representation (Argand diagram) of and its conjugate in the complex plane The complex conjugate is found by reflecting across the real axis In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign That is, if and are real numbers, then the complex conjugate of is The complex
  • Ancient Egyptian multiplication - Wikipedia
    In mathematics, ancient Egyptian multiplication (also known as Egyptian multiplication, Ethiopian multiplication, Russian multiplication, or peasant multiplication), one of two multiplication methods used by scribes, is a systematic method for multiplying two numbers that does not require the multiplication table, only the ability to multiply and divide by 2, and to add It decomposes one of
  • Continued fraction - Wikipedia
    A continued fraction is a mathematical expression written as a fraction whose denominator contains a sum involving another fraction, which may itself be a simple or a continued fraction [1] If this iteration (repetitive process) terminates with a simple fraction, the result is a finite continued fraction; if it continues indefinitely, the result is an infinite continued fraction The special
  • Square root algorithms - Wikipedia
    If , then is approximately k plus a fraction, the difference between a and k2 divided by the difference between the two squares: where The final operation, as above, is to multiply the result by the power of ten divided by 2; k is a decimal digit and R is a fraction that must be converted to decimal
  • Irreducible fraction - Wikipedia
    Irreducible fraction An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered) [1]
  • Decimal - Wikipedia
    Decimal fractions (sometimes called decimal numbers, especially in contexts involving explicit fractions) are the rational numbers that may be expressed as a fraction whose denominator is a power of ten [8] For example, the decimal expressions represent the fractions ⁠ 8 10 ⁠, ⁠ 1489 100 ⁠, ⁠ 79 100000 ⁠, ⁠ 1618 1000 ⁠ and ⁠ 314159 100000 ⁠, and therefore denote decimal
  • Repeating decimal - Wikipedia
    This, for cyclic fractions with long repetends, allows us to easily predict what the result of multiplying the fraction by any natural number n will be, as long as the repetend is known A proper prime is a prime p which ends in the digit 1 in base 10 and whose reciprocal in base 10 has a repetend with length p − 1
  • Rational number - Wikipedia
    The rational numbers ⁠ ⁠ are included in the real numbers ⁠ ⁠, which are included in the complex numbers ⁠ ⁠, while rationals include the integers ⁠ ⁠, which in turn include the natural numbers ⁠ ⁠ In mathematics, a rational number is a number that can be expressed as the quotient or fraction ⁠ ⁠ of two integers, a numerator p and a non-zero denominator q [1] For
