is the opposite of a number always negative?explain.?

No, because the opposite of -5 is 5 which is positive; the opposite of 0 is 0 which is neither positive nor negative.\n\nThis is why the expression "-x" should never be read as "negative x" but rather "the opposite of x" since if x itself were negative, -x would be positive.

Think of negative as also meaning "opposite."  \n\nSo "negative times negative" means taking the opposite of a negative.\n\nThe opposite of a negative is a positive.

They call ZERO an even number, who are they that mention like this?\n\nActually, odd numbers are start with 1, then 3, 5, etc., even numbers are start with 2, then 4, 6, etc.\n\nIf you check at the numbers system, then you can understand what meant by odd number, even number, negative number, natural number, whole number and others. \n\nSo, here the point is, ZERO actually is not a even number (the smaller even number start with 2), then there was no reason to tell you that why can call it an even number.

A negative number cannot have a square root.

okay the answer to that problem would be -10.\n1.  if you are subracting a negative from a negative, it's like you have 14 negatives and you take 4 away.  \n2. if you are subrtacting a positive from a negative, it's like adding more negatives on.  \nexample: -14 - 4 = -18\n3. If you are subtracting a negative from a positive, it's like adding more positives.\nexample: 14 - (-4) = 18\nin the problem above, you can see that i have minus a negative.  when my teacher taught me this she told me that i minus sign was like a negative.  and two negatives together makes a plus sign.  that might be confusing, but it helped me.  here's an example of what that would look like:\n14 + 4 = 18 . . . . easier?  \n\ni hope this helps and i didn't just confuse you.

Since the constant term is negative, the signs must be opposites. A little trial and error shows the answer to \nbe (x + 6)(x - 1)

Just multiply the numbers.  positives will get a positive answer.  Odd number of negatives will get a negative answer.  Even number of negatives will get a positive answer.

The same way you do algebra with regular numbers. Negative numbers are just the same.\n\nRemember that x - 3 is the same as x + -3.\n\nRemember the basics:\n\nAdding a bigger negative and smaller positive equals a negative number.-9+5=4\n\nAdding an equal negative and positive equals zero. -3+3=0\n\nAdding a smaller negative and a bigger positive equals a positive number. -3+12=9\n\nAdding two negative numbers equals a negative number. \n-3 + -4 = -7\n\nAnd remember that a negative number is the same as a positive number multiplied by -1. (ex: -3 = 3*-1)

x = -7\n\nMultiply two negatives and you get a positive

A negative number may be an integer, but not a whole number.\n\nWhole numbers are "counting numbers" starting with zero: 0, 1, 2, 3, 4, . . .\nIntegers are everything without a decimal point: . . . -3, -2, -1, 0, 1, 2, 3, . . .\n1934234 is a whole number and an integer\n-36 is an integer, but not a whole number\n27.5 and -3.12 are neither whole numbers nor integers

Yes, negative x positive always equals negative.  \n        negative x negative always equals negative\n        positive x positive always equals positive

Negative plus negative is ALWAYS negative.\n(-5) + (-3) = -8\n\nNegative minus negative may be negative, positive, or zero.\n(-5) - (-3) = (-5) + 3 = -2\n(-5) - (-5) = (-5) + 5 = 0\n(-5) - (-8) = (-5) + 8 = 3\n\nNegative plus positive works the same as negative minus negative. See the examples above.

You have probably figured out that no number will make this statement true. But don't forget about zero. \nYou will also find problems where even zero does not work. In those cases, "no solution" is the correct answer.

The (x-3)s cancel out because they will produce the same answer for all values of x.\n\n(x-5)/(5-x) produces an answer of -1 because they'll always be the opposite (negative) answer for all values of x.\n\nThe answer is -1

the closest you can get to an opposite for "not" is nothing.  literally, i mean like "   " because adding "not" makes whatever it goes with the opposite.  so the opposite of "not" is just to not have the "not"  :)

First you can only define even and odd for integers, so it only applies to {... -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...}\n\nAn integer is even if you divide it by 2 and have *no* remainder.  \nAn integer is odd if you divide it by 2 and have a remainder.\n\nThe set of even numbers:\n{... -6, -4, -2, 0, 2, 4, 6 ...}\n\nThe set of odd numbers:\n{... -5, -3, -1, 1, 3, 5, 7 ...}\n\nAn alternate definition is if the last digit of a number is 0, 2, 4, 6, 8 the number is even.\nIf the last digit of a number is 1, 3, 5, 7, 9, the number is odd.

For the first one, 4<-2<6 does become -2>x>-3 (you do have to flip the signs) and yes, it is still an "And" statement, just in reverse (or in other words, -2>x>-3 is the exact same thing as -3<x<-2). For the second one, you don't actually have to multiply by 10, but you should get the same answer either way. I got 0.84<x<1.76.
