Write the additive inverse of given number i.e., -33 ______.

For finding the additive inverse of a number, we must find a number whose sum with the given number yields zero.

Complete step-by-step answer:
In the number system, there are two ways of finding an inverse i.e., the additive inverse and multiplicative inverse. When the sum of two numbers is zero then one number is called the additive inverse of the other. In this way we can easily find a solution to our problem.

So, the number given for finding the additive inverse is -33.

If we add 33 to the above number, we get zero as a result. So, 33 is the additive inverse of the given number. It can be mathematically expressed as, $-33+33=0$.

Note: The key concept for solving this problem is the knowledge of additive inverse of a number. By using the additive identity, we can easily find a solution to our problem. It is helpful in understanding difficult conceptual problems.
