- A negative number is a number $x$ such that $x+y=0$ for some positive number $y$. In other words, a negative number is an object whose sum with some positive number equals the additive identity. A similar approach can be used to define other mathematical objects: $ 1 x=0$ is an object such that $a+x=a$. $ 2 x=\frac{1}{a}$ is an object such that $xa=1$.

- Less than zero. (Positive means more than zero. Zero is neither negative nor positive.) A negative number is written with a minus sign in front Example: −5 is negative five. Negative is sometimes abbreviated −ve.

Integers For each positive integer, there is a negative integer, and these integers are called opposites. For example, -3 is the opposite of 3, -21 is the opposite of 21, and 8 is the opposite of -8. If an integer is greater than zero, we say that its sign is positive.

What is negative zero? Zero is neither negative nor positive. By definition, a positive number is greater than zero. Similarly, a negative number is less than zero. Zero itself does not fit into either of those categories, and is thus neither negative nor positive; it is neutral. Negative zero then, is equal to -1 × 0, which equals 0.

What does it mean to raise a number to a negative power? A negative exponent is exactly the same as a positive one with one major exception: a negative power means divide 1 by that number. Sounds complicated but if you see it it's much simpler. 2=2/1. 25=25/1. 2^2=(2^2)/1.

Subtracting Positive and Negative Numbers Rule 3: Subtracting a negative number from a negative number—when you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you are adding a positive.

- 1.7 Negative numbers and the use of brackets. Numbers smaller than zero (shown to the left of zero on the number line in the figure below) are called negative numbers. We indicate they are negative by putting them in brackets as shown in the figure below.

Operations with Negative Numbers For example, +5 + (8) has a negative sum, since 8 is farther from zero than +5. Since 8 is 8 units from zero and +5 is 5 units from zero, the sum is (8  5) = 3. When subtracting with negative numbers on a number line, the subtraction sign means to go in the opposite direction of the directed distance that follows.

Negative number The relationship between negative numbers, positive numbers, and zero is often expressed in the form of a number line: Numbers appearing farther to the right on this line are greater, while numbers appearing farther to the left are less.

Introduction to Negative Numbers The whole numbers start at zero and count off to the right; these are the positive integers. The negative integers start at zero and count off to the left: Note the arrowhead on the far right end of the number line above. That arrow tells you the direction in which the numbers are getting bigger.

zero Zero is not nothing! It is a number that stands for nothing, and this is an important distinction. In many ways, zero is the most important of all numbers. When zero is added to or subtracted from a number, it leaves the number at its original value. Zero thus makes negative numbers possible.

Does negative zero exist? [closed] A common definition of negative is less than zero. In this sense, zero isn't negative (nor positive for a similar reason). But the opposite of zero is well defined: it is zero. The unary $+$ or $-$ operators can very well be applied to $0$, with no effect.

Basics of Positive and Negative Numbers Positive and negative numbers are all integers. Integers are whole numbers that are either greater than zero (positive) or less than zero (negative). For every positive integer, there’s a negative integer, called an additive inverse, that is an equal distance from zero.

- Negative number definition - math word definition. Numbers can be positive, negative or zero. Negative numbers are less than zero and usually mean a value that is a deficit ot shortage. Also can mean a number below some arbitrary reference point. When shown on a number line, they are the ones usually drawn on the left of zero. Number - math word definition.

- Whole numbers less than zero A negative integer is a negative whole number that is the opposite of a counting number. When we count, we start at 1 and count 1, 2, 3, etc. Negative integers are the opposite of those numbers: -1, -2, -3, and so on. Further explanation An integer is a whole number..

Negative Exponent: Definition & Rules Negative exponents have caused problems for math students as long as they have been defined. This lesson will shed some light on the negative exponent: what it means and how to work with it in a math problem. There is also a quiz at the end of the lesson.or example: 2^3 = 2*2 *2 = 8. The word exponent is from the Latin expo, meaning out of, and ponere, meaning place. The first recorded modern usage of the concept was in the 1500's. However, the concept of squared and cubed numbers dates back to ancient Babylon.

Basics of Positive and Negative Numbers You indicate a positive or negative number by using positive (+) and negative (–) signs. Although you don’t have to include a positive sign when you write positive numbers, you must always include the negative sign when you write negative numbers. Positive numbers are bigger, greater, or higher than zero.

- 1 A positive number multiplied by a negative gives a negative 20 x -4 = -80. 2  A positive number divided by a negative gives a negative 20 / -4 = -5. 3  A negative number multiplied by a negative gives a positive -20 x -4 = 80.  A negative number divided by a negative gives a positive -20 / -4 = 5.
