(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
A negative number divided by a negative number is a positive number.
Yes. 81 is a:- Real number - Rational number - Integer - Natural number - Counting number - Square number - Odd number
A negative number divided by a positive number will be a negative number. For example: -20 / 4 = -5 -100 / 2 = -50 Here are the other cases of division by positive or negative numbers. A negative number divided by a negative number would be a positive number. A positive number divided by a positive number would be a positive number. A positive number divided by a negative number would be a negative number.
It is a real number, a rational number, an integer.
You have to produce a paper in partnership with Paul Erdos to get an Erdos number of 1. If you produce a paper in partnership with someone who already has an Erdos Number, you get one more than your co-author(s). It is rumoured that baseball legend Hank Aaron has an Erdos number of 1 since he and Erdos both signed the baseball with which Aaron broke Babe Ruth's career home run record of 714 !
No, it does not. The Benford Law requires the numbers to span several orders of magnitude, Erdos numbers have a very small range.

Erdos' Conjecture on Arithmetic Progressions (Wikipedia.org)
Paul Erdos has written: 'Topics in the theory of numbers'
This is a very subjective question, especially considering that mathematics has several fields that go into such detail that specialists from one field can do little on advanced topics in a different field. However, some notable mathematicians include Pythagoras, Euler, and Erdos. (In fact, Erdos was a mathematician of such great fame that there is something called an Erdos number that people made up to keep track of how close they are to writing a paper with Erdos himself.)
Victor Erdos was born on February 16, 1972, in Toronto, Ontario, Canada.
Todd Erdos was born November 21, 1973, in Washington, PA, USA.
