# 100y – 100y

## 0    1    200y    100y Hint:

## The correct answer is: 0

### The given expression is 100y – 100yThere is one variable in the above expression. The variable is: ‘y’. There are two terms in the above expression. We have to perform the operations between them and find the right answer.If we see, both the terms contain the same variable. Such terms with the same variables are called “like terms.” And the terms with different variables are called “unlike terms.”For like terms, we can perform the operations between their coefficients by keeping the variable constant. It means we can treat each term as a constant and perform operations like normal operations on constants.For the above expression, we can perform an operation between the both the term as they have the same variable ‘y’. We will keep y constant. And perform subtraction between the coefficients.Let’s see the expression100y – 100y =(100 – 100)y100y – 100y = 0Therefore, the value of the equation is 0So option which is ’0’, is the right option.

We have to be careful about the variables. Only like terms operate with each other.
