What is inverse operation?

An inverse operation undoes the effect of another operation. For example, addition is the inverse operation of subtraction, and multiplication is the inverse operation of division. Applying an operation and its inverse leaves you with the original value.


What does the word inverse operation mean?

An inverse operation (for some operation) is, in a way, the opposite of another operation. For example, subtraction is the opposite of addition (if you add 7, then subtract 7, the subtraction will "undo" the addition - you get the original number back). Similarly, division is the inverse of multiplication, taking a root is the inverse of calculating a power, and the logarithm is also the inverse of calculating a power (the difference being that taking a root finds the unknown base, while taking the logarithm finds the unknown exponent).


What is an inverse operation?

An inverse operation is an operation that reverses the effect of the original operation. For example, addition and subtraction are inverse operations. 2 add 5 is 7, subtract 5 is 2. The subtraction of 5 reversed the effect of adding 5. Multiplication and division are also inverse operations. Two functions f and g are inverse if f(g(x)) = g(f(x)) = x.


What operation is the inverse operation of addition?

The inverse operation of addition is subtraction. Subtraction undoes addition by taking away a number from the sum to return to the original value.


How could you show the inverse operation of Exercise 5 above?

To show the inverse operation of Exercise 5, you could demonstrate how to undo the steps of Exercise 5 in reverse order, resulting in the original input. This would help illustrate how the inverse operation undoes the effects of the original operation.

What is the inverse of operation mean?

It is a second operation that "undoes" the first.For example, the inverse of "add 2" is "subtract 2";the inverse of "divide by 7" is "multiply by 7";the inverse of "take the reciprocal" is "take the reciprocal".

What is an inverse operation subtract 5?

The inverse operation for subtract 5 is add 5. This is because whatever number you start with, if you first "subtract 5" and then "add 5" or if you first "add 5" and then "subtract 5" you are back to the number you started with.

How do you use the inverse operation to add 23?

Using the inverse operation is probably the most clumsy way of obtaining the answer.To add 23 to some known number x, you would be required to find the number y such that subtracting 23 from y (the inverse operation) would result in x. Why on earth would you do that?


How n-8 is solve in inverse operation?

y = n - 8 In this case you start with n and then subtract 8. For the inverse operation you start at the end and replace each operation by its inverse. So "subtract 8" is replaced by "add 8". That is it. n = y + 8
