    k2tog: Knit two stitches together. k2tog tbl: Knit two stitches together, through the back loop. k3tog : Knit three stitches together. k-b: Knit through the back loop, or knit below. k tbl: Knit one through the back loop. kfb: Knit into the front and back of a stitch, an increase. kll: Knit left loop; an increase. krl: Knit right loop; an increase.

  3. Help:Displaying a formula - Wikipedia

    en.wikipedia.org/wiki/Help:Displaying_a_formula

    Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.

  4. Decrease (knitting) - Wikipedia

    en.wikipedia.org/wiki/Decrease_(knitting)

    K2tog tbl ("knit two together through the back loops") – This looks similar to the SSK or S1, K, PSSO, but is faster to work. Work to the two stitches to be decreased, then insert the right hand needle into the backs of the next two stitches (i.e. behind the left-hand needle, such that the two needles are anti-parallel in the stitches).

  5. Zero to the power of zero - Wikipedia

    en.wikipedia.org/wiki/Zero_to_the_power_of_zero

    The combinatorial interpretation of b 0 is the number of 0-tuples of elements from a b-element set; there is exactly one 0-tuple. The set-theoretic interpretation of b 0 is the number of functions from the empty set to a b-element set; there is exactly one such function, namely, the empty function. [1] All three of these specialize to give 0 0 = 1.

  6. Return-to-zero - Wikipedia

    en.wikipedia.org/wiki/Return-to-zero

    Return-to-zero, inverted (RZI) is a method of mapping for transmission. The two-level RZI signal has a pulse (shorter than a clock cycle) if the binary signal is 0, and no pulse if the binary signal is 1. It is used (with a pulse 3/16 of a bit long) by the IrDA serial infrared (SIR) physical layer specification. Required bandwidth for this kind ...

  7. Signed zero - Wikipedia

    en.wikipedia.org/wiki/Signed_zero

    Signed zero is zero with an associated sign.In ordinary arithmetic, the number 0 does not have a sign, so that −0, +0 and 0 are equivalent. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero), regarded as equal by the numerical comparison operations but with possible different behaviors in ...

  8. Trailing zero - Wikipedia

    en.wikipedia.org/wiki/Trailing_zero

    In such a context, "simplifying" a number by removing trailing zeros would be incorrect. The number of trailing zeros in a non-zero base-b integer n equals the exponent of the highest power of b that divides n. For example, 14000 has three trailing zeros and is therefore divisible by 1000 = 10 3, but not by 10 4.

  9. Transmission zeroes - Wikipedia

    en.wikipedia.org/wiki/Transmission_zeroes

    A few procedures can be followed for realizing passive two-ports with transmission zeroes. As long as transmission zeros are located at the origin or infinity, all that is needed is the application of Cauer 1 or 2 steps [clarification needed] to remove poles [clarification needed] from either the admittance or the impedance at the origin or infinity.
