    Perform the original operation on the condensed operands, and sum digits: 2 × 7 = 14; 1 + 4 = 5; Sum the digits of 500702: 5 + 0 + 0 + (7 + 0 + 2 = 9, which counts as 0) = 5; 5 = 5, so there is a good chance that the prediction that 6,338 × 79 equals 500,702 is right. The same procedure can be used with multiple operations, repeating steps 1 ...

  6. Creatinine - Wikipedia

    en.wikipedia.org/wiki/Creatinine

    One mg/dL of creatinine equals 88.4 μmol/L. The typical human reference ranges for serum creatinine are 0.5 mg/dL to 1.0 mg/dL (about 45 μmol/L to 90 μmol/L) for women and 0.7 mg/dL to 1.2 mg/dL (60 μmol/L to 110 μmol/L) for men. The significance of a single creatinine value must be interpreted in light of the patient's muscle mass.

  7. Multiplication sign - Wikipedia

    en.wikipedia.org/wiki/Multiplication_sign

    The multiplication sign (×), also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. [1] The symbol is also used in botany, in botanical hybrid names. The form is properly a four-fold rotationally symmetric saltire. [2]

    Figure 2 is used for the multiples of 2, 4, 6, and 8. These patterns can be used to memorize the multiples of any number from 0 to 10, except 5. As you would start on the number you are multiplying, when you multiply by 0, you stay on 0 (0 is external and so the arrows have no effect on 0, otherwise 0 is used as a link to create a perpetual cycle).

    Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:
