Additive Inverse Property: Definition & Examples The additive inverse of a number is what you add to a number to create the sum of zero. So in other words, the additive inverse of x is another number, y, as long as the sum of x + y equals zero. The additive inverse of x is equal and opposite in sign to it (so, y = -x or vice versa). For example, the additive inverse of the positive number 5 is -5. That's because their sum, or 5 + (-5) = 0.

Motivation Problems Multiplicative Inverse or Reciprocal. When the product of two numbers is one, they are called reciprocals or multiplicative inverses of each other. For example, and are reciprocals because. This is the motivation for the following property of fractions.where a and b are nonzero.The fraction is called the multiplicative inverse of (or reciprocal) and vice versa. Notice that a reciprocal (multiplicative inverse) can be formed from any common fraction by exchanging the positions of the numerator and denominator.The reciprocal of is, of is, and is.hen the product of two numbers is one, they are called reciprocals or multiplicative inverses of each other. For example, and are reciprocals because. This is the motivation for the following property of fractions.

Identities, Inverses, Symmetry, etc. The identity is zero, and the inverse is 6, because –6 + 6 = 0. For multiplication, the identity is one, because multiplying by one doesn't change anything. The inverse is the multiplicative inverse: the same number, but on the opposite side of the fraction line. For instance, suppose your number is –6, and you're multiplying.

INVERSE INSTRUCTIONS The denominator will be the numerator of the first factor. The numerator of the multiplicative inverse is 2 and the denominator is 3. This gives an answer of: All the examples in Reciprocal demonstrate that a number multiplied by its inverse gives a product of 1.NVERSE INSTRUCTIONS. Two numbers are multiplicative inverses of each other if the product of the numbers is one (1). Multiplicative Inverse is similar to the program MULTIPLY FRACTIONS except that you are to determine the second factor, which will be the multiplicative inverse of the first factor.

Additive Group An additive group is a group where the operation is called addition and is denoted . In an additive group, the identity element is called zero, and the inverse of the element is denoted (minus ). The symbols and terminology are borrowed from the additive groups of numbers: the ring of integers , the field of rational numbers , the field of real numbers , and the field of complex numbers are all additive groups. In general, every ring and every field is an additive group.

Inversive geometry To invert a number in arithmetic usually means to take its reciprocal. A closely related idea in geometry is that of inverting a point. In the plane, the inverse of a point P with respect to a reference circle (ø) with center O and radius r is a point P', lying on the ray from O through P such that. This is called circle inversion or plane inversion.

Inverse Cotangent The inverse cotangent is the multivalued function (Zwillinger 1995, p. 465), also denoted (Abramowitz and Stegun 1972, p. 79; Harris and Stocker 1998, p. 311; Jeffrey 2000, p. 124) or (Spanier and Oldham 1987, p. 333; Gradshteyn and Ryzhik 2000, p. 208; Jeffrey 2000, p. 127), that is the inverse function of the cotangent.

the absolute value of a number is the distance the number is from the zero point on the number line . The absolute value of a number or an expression is always greater than or equal to zero (i.e. nonnegative).see  lesson Additive Inverse of a Number. The opposite of a number. For example, the additive inverse of 12 is –12. The additive inverse of –3 is 3. Formally, the additive inverse of x is –x. Note: The sum of a number and its additive inverse is 0. See also.

Additive inverse For other uses, see analog and counterpart. In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.
