In like terms, one can only change the numerical coefficient. Terms containing the same variable raised to the same power are known as like terms.We can categorize the terms in an algebraic expression into two types - like and unlike terms. An example of an algebraic expression is 5x+7. The sign of each term that is to be subtracted is reversed and then the resulting expression is added normally.Īn algebraic expression (or) a variable expression is a combination of terms by operations such as addition, subtraction, multiplication, division, etc. The other way is to follow the horizontal method that requires writing the expressions to be subtracted below the expression from which it is to be subtracted. Then, taking up the like terms and then subtracting them accordingly. What is Subtraction of Algebraic Expressions?įor subtracting two or more algebraic expressions, it requires categorizing the terms in an algebraic expression into two types - like and unlike terms.
