What does reciprocals mean in mathematics.

In mathematics the harmonic mean sometimes called the subcontrary mean is one of several kinds of average and in particular one of the pythagorean means typically it is appropriate for situations when the average of rates is desired. If you have a number a it s reciprocal is the number b such that a b 1. 1 divided by the number examples. Every number has a reciprocal except 0 1 0 is undefined multiplying a number by its reciprocal.

The reciprocal of a number is. I ll assume you mean the reciprocal as in the multiplicative inverse. You can practice reciprocals by covering up parts of. A reciprocal or multiplicative inverse is simply one of a pair of numbers that when multiplied together equal 1 if you can reduce the number to a fraction finding the reciprocal is simply a matter of transposing the numerator and the denominator.

The reciprocal of 2 is 1 2 half the reciprocal of 10 is 1 10 0 1 when we multiply a number by its reciprocal we get 1. The harmonic mean can be expressed as the reciprocal of the arithmetic mean of the reciprocals of the given set of observations. It can mean many different things depending on the context.
