  2. Divisibility rule - Wikipedia

    en.wikipedia.org/wiki/Divisibility_rule

    (1 × 15 − 3 × 75 + 2 × 15) + (1 × 37 − 3 × 18 + 2 × 60) = −180 + 103 = −77 The result −77 is divisible by seven, thus the original number 15751537186 is divisible by seven. Another digit pair method of divisibility by 7. Method. This is a non-recursive method to find the remainder left by a number on dividing by 7:

  3. Fraction - Wikipedia

    en.wikipedia.org/wiki/Fraction

    Unit fractions can also be expressed using negative exponents, as in 21, which represents 1/2, and 22, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two, e.g. ⁠ 1 / 8 ⁠ = ⁠ 1 / 2 3 ⁠. In Unicode, precomposed fraction characters are in the Number Forms block.

  5. Division by zero - Wikipedia

    en.wikipedia.org/wiki/Division_by_zero

    For example, using single-precision IEEE arithmetic, if x = −2 −149, then x/2 underflows to −0, and dividing 1 by this result produces 1/(x/2) = −∞. The exact result −2 150 is too large to represent as a single-precision number, so an infinity of the same sign is used instead to indicate overflow.

  6. Rule of 72 - Wikipedia

    en.wikipedia.org/wiki/Rule_of_72

    Thus at 3.5% inflation using the rule of 70, it should take approximately 70/3.5 = 20 years for the value of a unit of currency to halve. [ 1 ] To estimate the impact of additional fees on financial policies (e.g., mutual fund fees and expenses , loading and expense charges on variable universal life insurance investment portfolios), divide 72 ...

  7. Euclidean division - Wikipedia

    en.wikipedia.org/wiki/Euclidean_division

    Using Euclidean division, 9 divided by 4 is 2 with remainder 1. In other words, each person receives 2 slices of pie, and there is 1 slice left over. This can be confirmed using multiplication, the inverse of division: if each of the 4 people received 2 slices, then 4 × 2 = 8 slices were given out in total. Adding the 1 slice remaining, the ...

  8. Turn (angle) - Wikipedia

    en.wikipedia.org/wiki/Turn_(angle)

    The turn (symbol tr or pla) is a unit of plane angle measurement that is the measure of a complete angle—the angle subtended by a complete circle at its center. One turn is equal to 2π radians, 360 degrees or 400 gradians.

  9. Pythagorean triple - Wikipedia

    en.wikipedia.org/wiki/Pythagorean_triple

    For instance, 38 2 = 1444, 2 × 27 2 = 1458, 3 × 22 2 = 1452, 5 × 17 2 = 1445 and 10 × 12 2 = 1440; the corresponding parabolic strip around n ≈ 1450 is clearly visible in the scatter plot. The angular properties described above follow immediately from the functional form of the parabolas.
