It is +q, since -q +(+q) = 0.
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.
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.
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)
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
Charge is charge, q. If you want it negative just add "-" by its value; some use -q to represent negative charges, too.
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.
An equation where q = 240
They are numbers that can be expressed as -p/q where p and q are positive integers.
What's the number for Q 97.8
An "opposite" is not a well defined term since there are additive opposites and multiplicative opposites and you have not specified which one.The absolute value of a rational number is the value of the number with a positive sign.Thus (abs(5/7) = 5/7and abs(-5/7) = 5/7
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).
