Answer. multiplicative inverse of 18 is 1/18.

Additive inverse of 17 is -17. (-17) is the additive inverse of 17.

Additive inverse refers to any number that when added to the original number gives the result as zero. For instance, the additive inverse of 8 is -8 as 8 + (-8) = 0.

Since the additive inverse of 15 is -15, additive inverse is also known as the opposite number.

The additive inverse of 16 is -16.

Answer: 7 is the additive inverse of -7.

Note that over GF(2), the additive inverse of 1 is 1 because 1+1=0 and the multiplicative inverse of 1 is 1.

Dividing by a number is equivalent to multiplying by the reciprocal of the number. Thus, 7 ÷7=7 × 1⁄7 =1. Here, 1⁄7 is called the multiplicative inverse of 7. Similarly, the multiplicative inverse of 13 is 1⁄13.

For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0.

Inverse Properties of Addition and Multiplication

• Example 1: 5 + (-5) = 0 -5 is the opposite of 5.
• Example 2: -4 + (4) = 0 -4 is the opposite of 4.
• Example 3: 10.
• -10 -10 is the opposite of 10.
• Example 4: -12.
• +12 12 is the opposite of – 12.
• Inverse Property of Multiplication says that any number multiplied by its reciprocal is equal to one.

The multiplicative inverse of 1/2 is 2.

The inverse composition rule This is because if f and g are inverses, composing f and g (in either order) creates the function that for every input returns that input.

An inverse variation can be represented by the equation xy=k or y=kx . That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 .

Notation. The inverse of the function f is denoted by f -1 (if your browser doesn’t support superscripts, that is looks like f with an exponent of -1) and is pronounced “f inverse”. Although the inverse of a function looks like you’re raising the function to the -1 power, it isn’t.

An inverse relationship is one in which the value of one parameter tends to decrease as the value of the other parameter in the relationship increases. It is often described as a negative relationship.

Inverse order of maturity means that if you make an extra loan payment, it gets applied to the final payment that would be due at maturity. In other words, you can’t make 2 payments this month and expect to not have to make your loan payment for 2 months.

Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on. Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry.
