Why is the reciprocal of the opposite of a nonzero number the opposite of the reciprocal of the number?
Taking the reciprocal (multiplicative inverse) does not affect the positive or negative status of an integer. So the reciprocal of a negative number is negative and the reciprocal of a positive number is positive. The reciprocals will be opposites (positive/negative) just as the original numbers were.
How do you solve an equation if you have simplified and are left with a negative variable?
the negative variable would mean the opposite of. so therefore if u have -x= 4 ur answer would be the opposite of four which is negative 4.
What are opposite numbers?
Opposite numbers are another words for negative numbers.-4 is opposite of +45,6,7,8,9, and so on
How Minus 3 multiply minus 3 9?
-3 x -3=9 A rule in pre-algebra summarizes in a problem when their is an odd amount of odd - (negative numbers) then the answer is negative, if it is even is is positive.So the problem is asking, the opposite of three times the opposite of three equals 9, so lets take one of those opposites away. The opposite of three times three equals opposite of nine. (If you haven't noticed, negative and opposite are interchangeable.) And another opposite and get the original problem, the opposite of three times the opposite of three equals 9. So the opposite of the negative nine from the first multiply, is positive nine.Example-3 x 3= -9 (1 negative)-3 x -3= 9 (2 negative, the opposite of the opposite.)Tips- It is easier to think as two - - = +,DO NOT MISTAKE THIS WITH ++=+, IT DOES NOT EQUAL A NEGATIVE.THIS ONLY WORKS WITH MULTIPLYING AND DIVIDING.(in basic math)
What is one half to the negative first power?
One half to the negative first power is equal to the reciprocal of one half raised to the first power. The reciprocal of one half is two, so (1/2)^(-1) = 1 / (1/2) = 1 * 2 = 2.
