## What are Inverse Operations?

❶Then multiply each side by 4.

Now, we multiply the 1st row of the first matrix and 2nd column of the second matrix. The answer goes in position 1, 2. Now we multiply 2nd row of the first matrix and the 1st column of the second matrix.

The answer goes in position 2, 1. Finally, we multiply 2nd row of the first matrix and the 2st column of the second matrix. The answer goes in position 2, 2. No other question has ever moved so profoundly the spirit of man.

I am ever more convinced that the necessity of our geometry cannot be proved -- at least not by human reason for human reason.

While adding a certain amount to a given quantity, it increases by that amount, whereas subtracting the same amount to the new increased quantity you get the original one again.

You are given 35 apples. You add 5 apples more to them. Now the total amounts of apples you have are. The reason behind is that we are dealing with an equation. An equation is balanced. If exactly the same thing is done to both sides of the equation, it will remain balanced.

Division is the inverse operation of multiplication and vice versa. While multiplying a amount x to a given quantity, it increases x times, whereas dividing the same amount to the new increased quantity you get the original one again.

We know that when a number is dived by 1, its value does not change. So turn it upside down and it becomes the reciprocal of that number. A point to be noted is that every number has a reciprocal except zero. Reciprocal of zero is not defined.

In another words, two operations are said to be inverse of each other, if one of them undoes the effect of another. Addition and Subtraction are inverse operation of each .

### Privacy FAQs

In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa.
