Is a negative plus a positive a positive?

If, and only if the positive value is > the negative value.


Do Positive numbers have negative square roots?

Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.


If a negative number squared is positive why isn't the square root of a positive number negative?

When a negative number is squared, the negative sign is essentially squared along with the number, resulting in a positive value. However, when taking the square root of a positive number, we are looking for the value that, when squared, gives us the original positive number. Since both a positive and negative number can square to the same positive value, the convention is to consider the principal (positive) square root by default. The negative square root is also a valid solution in many contexts, but for simplicity and consistency, the positive square root is typically chosen.


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.


What are the rules for adding numbers whose signs are different?

Positive plus positive is positive. Negative plus negative is negative. Positive plus negative is positive if the absolute value of the positive number is greater than the absolute value of the negative one. Positive plus negative is negative if the absolute value of the negative number is greater than the absolute value of the positive one.

What is value of square of negative iota?

The square of negative iota will be the same as the square of positive iota (i.e. -1) because when a negative number is multiplied by a negative number, the answer is positive.


Will a negative number to the fifth power be a positive or a negative value explain?

What is the square root of a square?

√(a^2) That is |a| (the absolute value of a) Because if a is positive, a^2 is positive, and since √ is a positive square root, √(a^2) is a. If a is negative, a^2 is positive, and since √ is a positive square root, √(a^2) is -a. So if a is positive, √(a^2) is positive (which is a) If a is negative, √(a^2) is also positive (which is -a) So √(a^2) is |a| for every a.


What is the value of chi square test positive or negative?

There must be some value otherwise nobody would do them. On that basis, the value must be positive.


What negative numbers are less than positive numbers. Does this mean that the absolute value of a negative number must be less than the absolute value of a positive number Explain?

No it is not true. The absolute value of a number is simply the value of the number with a positive sign.


Is it possible to find the square root of a negative number in the real number system?

No. There is no real number which multiplied by itself forms a negative number.A negative times a negative is a positive, and only a positive times a negative is a negative.However, in calculus there is an "imaginary value" (called i ) which represents the square root of -1.Square roots of larger negative numbers are represented by the square of the absolute value times i .


Does a positive value multiplied by a negative value equal a positive?

No, the product of the multiplication of a positive and a negative value is negative.


Is a negative plus a positive a positive?

If, and only if the positive value is > the negative value.

Why -3 is not the answer to square root of 9?

It is - as well as positive 3. Multiplying a negative number by another negative always results in a positive value. Therefore the square root of 9 can be either 3 or -3.


A teacher wrote two numbers on the board negative 10 and positive 7 On the lines below explain which number has the larger absolute value and why?

Negative 10 because the absolute value of a number is the positive and negative form of that number. For example: The absolute value of 9 is positive 9 and negative 9. Therefore, it would be greater than the absolute value of any number below it.


What does a negative add a positive equal?

If the absolute value of the negative is bigger than that of the positive, then the answer is negative. If the absolute value of the negative is the same, then zero. If the absolute value of the negative is smaller, then positive. Absolute value is the value ignoring the sign.
