  2. Method of complements - Wikipedia

    en.wikipedia.org/wiki/Method_of_complements

    In grade schools, students are sometimes taught the method of complements as a shortcut useful in mental arithmetic. [3] Subtraction is done by adding the ten's complement of the subtrahend, which is the nines' complement plus 1. The result of this addition is used when it is clear that the difference will be positive, otherwise the ten's ...

    Five and ten: Sums of the form 5 + x and 10 + x are usually memorized early and can be used for deriving other facts. For example, 6 + 7 = 13 can be derived from 5 + 7 = 12 by adding one more. [36] Making ten: An advanced strategy uses 10 as an intermediate for sums involving 8 or 9; for example, 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14. [36]

    Subtraction of numbers 0–10. Line labels = minuend. X axis = subtrahend. Y axis = difference. Subtraction is usually written using the minus sign "−" between the terms; that is, in infix notation. The result is expressed with an equals sign. For example, = (pronounced as "two minus one equals one")

    The 9's complement of any one-digit decimal number d is 9-d. So the 9's complement of 4 is 5 and the 9's complement of 9 is 0. Similarly, the 11's complement of 3 is 8. In a decimal machine with n dials the 9's complement of a number A is: = and therefore the 9's complement of (A-B) is:

  6. Mental calculation - Wikipedia

    Since 9 = 10 − 1, to multiply a number by nine, multiply it by 10 and then subtract the original number from the result. For example, 9 × 27 = 270 − 27 = 243. This method can be adjusted to multiply by eight instead of nine, by doubling the number being subtracted; 8 × 27 = 270 − (2×27) = 270 − 54 = 216.
