A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
Is -(x) a negative number or positive number?

Can -x represent a positive number?
Yes, if x is a negative number.
Absolute value of 1.5?
The absolute value of a positive number is the same number - in this case, 1.5. The absolute value of a negative number is the number, without the sign. Note that the absolute value of an expression like (-x) is not necessarily (x); rather, you have to separately consider the case that x is positive, or that x is negative. For example, the absolute value of x is x (if x is positive), or (-x) (if x is negative).
When multiplying a negative number by a positive number is the result going to be negative or positive?
The result will always be negative. Positive X Positive = Positive Negative X Negative = Positive Positive X Negative = Negative
What is negative 10 times negative 5?
-10 x -5 = +50A negative times a negative will always equal a positive number.A negative times a positive will always equal a negative number.A positive times a positive will always equal a positive number.- x - = +- x + = -+ x + = +
Does -3x have a positive or negative value?
It depends on what the value of x is. If x is a positive number, then it will be negative because a negative number multiplied by a positive number is negative. If x is a negative number, then it will be positive because the product of two negative numbers is always a positive number.
When you mutiply a positive number by a negative one what is the sign of the answer?
The answer will ALWAYS be negative positive x negative=negative and vice versa positive x positive= positive
Explain why x does not necessarily represent a positive number?
x may not always represent a positive number because there are equations that make a variable a negative number
What is the rule for determining the sign of the product of two fractions?
It is the same as determining the sign of the product of two integers;+ x + = ++ x - = -- x + = -- x - = +ORIf only positive numbers are multiplied, the result is positive.If positive and an even number of negative numbers (for example, + x - x -) are multiplied, the result is positive.If positive and an odd number of negative numbers (for example, + x + x -) are multiplied, the result is negative.If an even number of negative numbers (for example, - x -) are multiplied, the result is positive.If an odd number of negative numbers (for example, - x - x -) are multiplied, the result is negative.Remember the rule:Product of a positive and a positive fraction is always positive.Product of a positive and a negative fraction is always negative.Product of a negative and a positive fraction is always negative.Product of a negative and a negative fraction is always positive.Examples:½ * ¼ = 1/8½ * -¼ = -1/8-½ * ¼ = -1/8-½ * -¼ = 1/8Source: www.icoachmath.com
X x x is always positive find a counter example?
0 * 0 is not positive.
What does a negative number multiplied by a negative number equal to?
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
Why under root -2 is not a real number?
Because if x were the square root of -2 then x*x = -2But if x were a negative real number, then x*x would be positive and if x were a positive real number, then x*x would still be positive. Therefore, there is no such x.
How do you define a positive real number?
Let 'x' be a positive real number. x|x≥0, xεR
Is -(x) a negative number or positive number?
It is a positive reciprocal. x-a = 1/xa or equivalently, (1/x)a
A positive is divided by a negative is the answer negative or positive?
previous answer: "the answer is - (negative)"I'd also like to add some steps and explainations to that.First, lets set a variable for the number---lets say x& y. If the positive number is x, and the negative one is y(lets make it -y to make it more clear), then the answer will equal x/-y. You can also write it into x/-y=x*1/-y or x*-(1/y). Since a negative number times a positive number will always be negative, then no matter what number you put for x or y, the answer will always be negative.The result will be negative.
