  2. Percent sign - Wikipedia

    en.wikipedia.org/wiki/Percent_sign

    The percent sign % (sometimes per cent sign in British English) is the symbol used to indicate a percentage, a number or ratio as a fraction of 100. Related signs include the permille (per thousand) sign ‰ and the permyriad (per ten thousand) sign ‱ (also known as a basis point ), which indicate that a number is divided by one thousand or ...

    50 / 100 × 40 / 100 = 0.50 × 0.40 = 0.20 = 20 / 100 = 20%. It is not correct to divide by 100 and use the percent sign at the same time; it would literally imply division by 10,000. For example, 25% = 25 / 100 = 0.25, not 25% / 100, which actually is 25 ⁄ 100 / 100 = 0.0025.

    3. Between two groups, may mean that the second one is a proper subgroup of the first one. ≤ 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".

  9. Relative change - Wikipedia

    en.wikipedia.org/wiki/Relative_change

    The relative change is independent of the unit of measurement employed; for example, the relative change from 2 to 1 m is −50%, the same as for 200 to 100 cm.The relative change is not defined if the reference value (v ref) is zero, and gives negative values for positive increases if v ref is negative, hence it is not usually defined for negative reference values either.

  10. Equality (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Equality_(mathematics)

    For any real numbers a, b, and c, if a = b, then ac = bc (here, F ( x) is xc ); For any real numbers a, b, and c, if a = b and c is not zero, then a / c = b / c (here, F ( x) is x / c ). Reflexive property: For any quantity a, a = a. Symmetric property: For any quantities a and b, if a = b, then b = a.

  11. Percentage point - Wikipedia

    en.wikipedia.org/wiki/Percentage_point

    For example, moving up from 40 percent to 44 percent is an increase of 4 percentage points (although it is a 10-percent increase in the quantity being measured, if the total amount remains the same). In written text, the unit (the percentage point) is usually either written out, [2] or abbreviated as pp , p.p. , or %pt. to avoid confusion with ...
