Multiplicative Inverse Of Integers

Inverse property of multiplication | Arithmetic properties | Pre-Algebra | Khan Academy

Finding the multiplicative inverse of positive integers is the same as natural numbers . Just like positive integers, the product of a negative number and its reciprocal must be equal to 1. Thus, the multiplicative inverse of any negative number is its reciprocal. For example, × = 1, therefore, the multiplicative inverse of -6 is -1/6. Note that the multiplicative inverse of a negative number is always negative. And, in the multiplicative inverse of a negative integer, the negative sign will attach to the numerator, and not with the denominator.

Additive Inverse And Multiplicative Inverse

There are two properties of numbers: multiplicative inverse and additive inverse property related to the multiplication and addition operation respectively. For a number x, – x is the additive inverse and 1/x is the multiplicative inverse. Let us understand the difference between additive inverse and multiplicative inverse with the help of the following table:

Additive Inverse

What Is The Inverse Of A Number

A number can have two inverses. One inverse is the additive inverse, which is the value that when added with the original number will equal zero. Another inverse of a number is the multiplicative inverse, or reciprocal. When a reciprocal is multiplied by the original number, the product is always 1.

Using Properties Of Real Numbers

For some activities we perform, the order of certain operations does not matter, but the order of other operations does. For example, it does not make a difference if we put on the right shoe before the left or vice-versa. However, it does matter whether we put on shoes or socks first. The same thing is true for operations in mathematics.

What Is Additive Inverse

Mathematics Quick Revision of inverse trigonometric function for CBSE

The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa. We know that, 7+ =0. Thus -7 is the additive inverse of 7 and 7 is the additive inverse of -7.

Properties Of Inverse Operations

  • Inverse Additive Property
  • The value, which, when added to the original number gives 0, is known as the additive inverse.

    Suppose, x is the original number, then its additive inverse will be minus of x, i.e., $-$$\text$, such that:

    $\text = 0$

    For example, $6+=0$. Hence, $6$ is the additive inverse of 6 and vice versa.

    Suppose, $-$$\text$ is the original number, then its additive inverse will be the positive value of x, i.e., x.

  • Inverse Multiplication Property
  • The value, which, when multiplied to the original number gives 1, is known as the multiplicative inverse.

    Suppose, x is the original number, then its multiplicative inverse will be the reciprocal of $\text$, i.e.,$\frac}$, such that:

    $\text\times\frac}=1$

    For example, $6\times\frac=1$. Hence, $\frac$ is the multiplicative inverse of 6 and vice versa.

    Suppose, $\frac$ is the original number, then its multiplicative inverse will be reciprocal of $\frac$, i.e., $x$.

    For example: multiplicative inverse of $\frac$ is $\frac$.

    The Inverse Of A Trigonometric Function

    The trigonometric functions are the functions that relate the right-angled triangle angle with the ratios of the side of the triangle.

    Ex: sin = Opposite side/Hypotenuse. So, we find the angle of the triangle by using this formula. What if we have to calculate the hypotenuse of a triangle if an angle is given. Then we will use the inverse function to calculate the hypotenuse. So, the inverse is written as

    = sin-1 is the inverse of the trigonometric sine function.

    Similarly, cos = Base/Hypotenuse. So, inverse is = cos-1.

    Tan = Opposite side/ Base. So, inverse is = tan-1 .

    Multiplicative Inverse Of 0

    As per the definition of multiplicative inverse, it is the number that when multiplied to the original number results in 1 as the product. But with 0, we know that the product of 0 with any number is always 0. So, the multiplicative inverse of 0 does not exist.

    We can also understand this using the properties of division which states that the division of any number by 0 is not defined. The multiplicative inverse of 0 can be written as 1/0, but its value is not defined. So, it does not exist.

    Inverse Property Of Logarithms

    It is the inverse of an exponent, according to the definition of a logarithm. As a result, the inverse of an exponential function is a logarithmic function. Recall what it means to be a functions inverse. When two inverses are added together, they equal x. As a result, if f=bx and g=logb x, then: fg=blog bx=x and gf=logb bx=x

    These are known as the Inverse Logarithm Properties. Lets tackle the following issues. The Inverse Properties of Logarithms will be used.

    1.Look for 10log56.

    We can see from the first property that the bases cancel each other out.

    56 eln6 eln2 = 10log56

    Here, e and the natural log cancel out, leaving us with 6.2=12.

    2.Look for log4 16x.

    The second property will be used in this case. Also, change 16 to 4^2.

    Log4 16x=log 4 x=log 4 42x=2x

    3.Determine the inverse of f=2e^x-1.

    Replace f with y. Then, reverse x and y.

    y=2e^x1

    x=2e^y1

    We must now isolate the exponent and compute the logarithm of both sides. Also, to begin, divide by two.

    x/2=e^y1

    ln=ln e^y1

    Remember the Inverse Properties of Logarithms we discussed previously in this concept? When we apply logb bx=x to the right side of our equation, we get . Determine the value of y.

    ln=y1

    As a result, ln+1 is the inverse of 2e^y-1.

    Properties Of Real Numbers

    Real numbers have unique properties, which makes them particularly useful in everyday life.

  • Real numbers are an ordered set of numbers. This means real numbers are sequential. The numerical value of every real number fits between the numerical values of two other real numbers. Everyone is comfortable with this concept since all measurements depend upon the fact that some numbers have a greater value than other numbers. Ten is greater than five, and five is greater than four, and so on.
  • We never run out of real numbers. The variety of real numbers available is not fixed. There is an infinite number of values available. The availability of numbers expands without end. Real numbers are not simply a finite row of separate points on a number line. There is always another real number whose value lies between any two real numbers.
  • When real numbers are added or multiplied, the outcome is always another real number.
  • With these three marks in mind, the question is:

  • How can we practice real numbers in practical calculations?
  • What rules employ?
  • How should numbers be added, multiplied, subtracted, and divided?
  • What scope do we have?
  • Does it matter what we do first? second? third? fourth?
  • Can we add a streak of numbers together in any order?
  • Will the outcome be the same nevertheless of the order we choose?
  • Can we multiply a streak of numbers together in any order?
  • Will the concluding answer be the same nevertheless of the order we choose?
    • Associative Property
