# Is negative 1 and 1 the same thing?

## Is negative 1 and 1 the same thing?

In mathematics, −1 (also known as negative one or minus one) is the additive inverse of 1, that is, the number that when added to 1 gives the additive identity element, 0. It is the negative integer greater than negative two (−2) and less than 0.

Why does a negative and a negative equal a positive?

Explanation: We know that negative times anything means that it will change the sign. Ideally, the second negative should change the sign of our original number (which is also negative). So, our original negative sign is changed into a positive sign when a negative is multiplied to it.

What is the absolute value of negative 1?

Explanation: The absolute of a negative number is the number without the negative sign. To be more precise, the absolute of a negative number, x<0 , can be obtained by multiplying −1 , i.e. |x|=−x .

### Do negative and positive numbers have the same value?

A positive number has a value greater than zero. Its sign is positive, but it is usually written without a plus sign in front of it (e.g., 4, 51 rather than +4, +51). A negative number has a value less than zero. Its sign is considered to be negative and it is written with a minus sign in front of it (e.g., -2, -23).

Why is a number times 1 always equal to itself?

What is the multiplicative identity property of 1? According to the multiplicative identity property of 1, any number multiplied by 1, gives the same result as the number itself. It is also called the Identity property of multiplication, because the identity of the number remains the same.

Is negative and minus the same thing?

When talking about the operators themselves, then the opposite of “plus” is “minus”. So when talking about the property of a number, then the opposite of “positive” has to be “negative”.

## What does a negative divided by a negative equal?

positive number
Rule 3: a negative number divided by a negative number equals a positive number. Two negatives make a positive, so a negative number divided by a negative number equals a positive number. For example, -8 / -2 = 4.

Do opposites have the same absolute value?

Two numbers are opposites if they have the same absolute value but different signs. Opposites are the same distance from 0 on a number line, and they are on opposite sides of 0. The opposite of 0 is 0.

Why is there the same number of negative integers as positive integers?

Since opposites are the same distance from the origin, they have the same absolute value. For example, the absolute value of “negative 10” is ten, and the absolute value of “positive 10” is also 10. The absolute value of zero is zero.

### Is 1 to the power of anything always 1?

Explanation: According to the exponent rule, any number raised to the power of one equals the number itself.

What does the negative symbol on a number mean?

The negative symbol applies only to the number it is paired with. The other thing to note is that the addition symbol (+) tells us to move to the right of the number line while the subtraction symbol (-) tells us to move to the left of the number line. Let’s look at some examples. Here is the number line again.

What’s the difference between a subtraction and a negative number?

The first thing to understand is the difference in the meaning between the subtraction symbol (-) and the negative number symbol (-). They both look the same but have different meanings. The subtraction symbol tells us which direction we want to go along the number line. The negative symbol applies only to the number it is paired with.

## What’s the difference between positive and negative correlations?

Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. Negative correlation or inverse correlation is a relationship between two variables whereby they move in opposite directions.

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

Taking the square root of a negative number isn’t impossible, it’s just not in the set of numbers that you started with (the set of positive and negative numbers, along with \$0\$). Take any negative number and call it \$a\$. We’re going to try and find \$a\$’s square root.
