The additive opposite of the rational number q is -q. One of q and -q must be non-negative and that is its absolute value.

The assertion in the question is not always true. Multiplying (or dividing) 0 by a negative number does not yields 0, not a negative answer.Leaving that blunder aside, let p and q be positive numbers so that p*q is a positive number.Thenp*q + p*(-q) = p*[q + (-q)] = p*[q - q] = p*0 = 0that is p*q + p*(-q) = 0Thus p*(-q) is the additive opposite of p*q, and so, since p*q is positive, p*(-q) must be negative.A similar argument works for division.

All integers and ratios between two integers are rational numbers. They are defined as p/q where p and q are integers and q is not 0. Therefore -41 is a rational number (and a negative integer as well).

q = Ne N = q/e Where: q = charge that can move N = number of electrons gained or lost e = elementary charge (1.602x10^-19)

Charge is charge, q. If you want it negative just add "-" by its value; some use -q to represent negative charges, too.

you have to write an algebraic expression. your number can be any thing you want... lets call it (q) the sum means you add the numbers. so... q + 23 the word (IS) in algebra means equal to so... q + 23 = 20 so what number added to 23 will equal to 20 the answer is negative 3 q=-3

All integers and ratios between two integers are rational numbers. They are defined as p/q where p and q are integers and q is not 0. Therefore -41 is a rational number (and a negative integer as well).

Try it by contradiction.Suppose that z is irrational, but -z is rational. That means that -z = p/q for some integers p and q. That yields a contradiction because z= -(-z) = ????

The negative of a negative number is a positive number.

In number systems Rational number is not represented just by q . they are represented in the form of p and q . P/q is rational number where q is not equal to zero.

yes.not only -5 but also all negative whole numbers and fractions are rational as they can be written as p/q form where p and q are two integers.
