Question

How many terms are there in this expression?
5  + 2y + 7?

  1. 3
  2. 10
  3. 14
  4. 20

Hint:

The above expression is an algebraic expression. An algebraic expression consists of two components, variable and constant. Variable is a quantity which doesn't have any fixed value. It is generally represented by alphabets. Constant is a quantity having fixed value. Now, according to the question we have to find the number of  terms in the expression.

The correct answer is: 3


    The given expression is 5+2y+7.
    The above expression consists of three constants and 1 variable y. They are all related to each other with different operations. We have to find number of terms in the given expression. A term is a quantity which is counted as single unit. It can be a number, a variable or combination of variable and constant or combination of two variables using the operation of multiplication and division. The operations of addition and subtraction create seperate terms. But the multiplication and division doesn't form two separate terms. They are generally considered as single unit. Now, the above expression has two plus signs. It means there are three terms connected to each other using the plus signs. The three terms are '5', '2y' and '7'.
    Therefore, option (a) which is '3' is the right option.

    We have to keep in mind that only sign '+' and '-' seperate the terms.
