Q..

## What number is the opposite of 8?

-1/8Answer and Explanation: The opposite reciprocal of 8 would be -1/8. The fraction that is equal to the whole number 8 would be 8/1. When that is flipped to make its…

## What is the sum of two negative numbers?

Rule: The sum of two negative integers is a negative integer.

## Why is the sum of any number and its opposite always equal to zero?

Zero is called the identity element of addition. The order in which you add two numbers does not change the result. … The opposite of a sum of real numbers is equal to the sum of the opposites.

## Is 0 a real positive number?

An integer is a whole number that can be either greater than 0, called positive, or less than 0, called negative. Zero is neither positive nor negative. … Zero is called the origin, and it’s neither negative nor positive.

## Is Pi a real number?

Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That’s because pi is what mathematicians call an “infinite decimal” — after the decimal point, the digits go on forever and ever.

## What is a true number?

The real numbers include all the rational numbers, such as the integer −5 and the fraction 4/3, and all the irrational numbers, such as √2 (1.41421356…, the square root of 2, an irrational algebraic number). Included within the irrationals are the transcendental numbers, such as π (3.14159265…).

## What is the opposite of zero on a number line?

Given a nonzero number, , on a number line, the opposite of , labeled , is the number such that: ▪ 0 is between and . The distance between 0 and is equal to the distance between 0 and . The opposite of 0 is 0. The set of whole numbers and their opposites, including zero, are called integers.

## Do imaginary numbers exist?

Essentially, an imaginary number is the square root of a negative number and does not have a tangible value. While it is not a real number — that is, it cannot be quantified on the number line — imaginary numbers are “real” in the sense that they exist and are used in math.

## Does Z+ include zero?

Z+ is the set of all positive integers (1, 2, 3, …), while Z- is the set of all negative integers (…, -3, -2, -1). Zero is not included in either of these sets .

## Is Number 1 odd or even?

An odd number is an integer when divided by two, either leaves a remainder or the result is a fraction. One is the first odd positive number but it does not leave a remainder 1. Some examples of odd numbers are 1, 3, 5, 7, 9, and 11. An integer that is not an odd number is an even number.

## What is the opposite of 13?

There are no categorical antonyms for thirteen. The numeral thirteen is defined as: The cardinal number occurring after twelve and before fourteen, represented in Roman numerals as XIII and in Arabic numerals as 13.

## What is the sum when a number is added to its opposite?

Lesson Summary When negative integers, which are whole numbers that are less than 0 and are located to the left of 0 on a number line, are added to their opposite, the sum is 0.

## Is zero an equal number?

Zero is an even number. In other words, its parity—the quality of an integer being even or odd—is even. This can be easily verified based on the definition of “even”: it is an integer multiple of 2, specifically 0 × 2. … In this sense, 0 is the “most even” number of all.

## Is 0 a real or imaginary number?

The answer is ‘both’ but the justification is different than given. An imaginary number is the square root of a nonpositive real number. Since zero is nonpositive, and is its own square root, zero can be considered imaginary.

## What type of number is 0?

0 is a rational, whole, integer and real number. Some definitions include it as a natural number and some don’t (starting at 1 instead).

## Is Infinity odd or even?

There are no numbers bigger than infinity, but that does not mean that infinity is the biggest number, because it’s not a number at all. For the same reason, infinity is neither even nor odd.

## What are the rules for positive and negative numbers?

The Rules:RuleExample+(+)Two like signs become a positive sign3+(+2) = 3 + 2 = 5−(−)6−(−3) = 6 + 3 = 9+(−)Two unlike signs become a negative sign7+(−2) = 7 − 2 = 5−(+)8−(+2) = 8 − 2 = 62 more rows

## Is zero considered its own opposite?

The number zero is neither positive nor negative. Zero is its own opposite; so +0 = −0. That is, zero steps to the right is the same as zero steps to the left. A negative number is always less than zero.

## Is Pi an imaginary number?

Every real number is a complex number. Therefore π, which is a real number, is a complex number. π is not an imaginary number, which are numbers in the form of xi, x∈R.

## What is not a real number?

A non-real, or imaginary, number is any number that, when multiplied by itself, produces a negative number. Mathematicians use the letter “i” to symbolize the square root of -1. An imaginary number is any real number multiplied by i. For example, 5i is imaginary; the square of 5i is -25.
