After applying an arithmetic operation to two operands and getting a result, you can use this procedure to improve your confidence that the result is correct.

(B) Correlation between GC3 and P REC, the proportion of genes detected as recombinant by PHI test [] in the class, for all 14 bacterial datasets showing sufficient evidence of recombination (). Correlations between the mean GC3 and mean recombination rate of each class are reported. (A) Correlation between GC3 and coalescent-based estimates of recombination rate for Homo sapiens ( Hsap) and Stretococcus pyogenes ( Spyo). For Spyo, recombination rate is expressed as the value of rho parameter in ClonalOrigin [] inferences, which is scaled by arbitrary coalescent time units; a subset of 437 genes out of 478 core genes was used, after removal of the 41 genes showing no convergence of the rho estimate (correlation on the full 478 core genes yields a R 2 of 31%, see ). Biologie des microorganisms pdf converter 2017. For Hsap, recombination rate is expressed as cM∙ Mb-1; a subset of 600 genes out of the 16,346 human genes is shown as a representative of 1,000 random samples (mean R 2 is 55%, see Main Text).

Sum the digits of the first operand; any 9s (or sets of digits that add to 9) can be counted as 0. If the resulting sum has two or more digits, sum those digits as in step one; repeat this step until the resulting sum has only one digit.

Repeat steps one and two with the second operand. You now have two one-digit numbers, one condensed from the first operand and the other condensed from the second operand. (These one-digit numbers are also the remainders you would end up with if you divided the original operands by 9; mathematically speaking, they're the original operands modulo 9.) Apply the originally specified operation to the two condensed operands, and then apply the summing-of-digits procedure to the result of the operation. Sum the digits of the result you originally obtained for the original calculation. If the result of step 4 does not equal the result of step 5, then the original answer is wrong. If the two results match, then the original answer may be right, though it isn't guaranteed to be. Check out Ebook 'Mind Math' from Dr.
