Some important Facts about Algebraic Expressions worksheet for class 7
- Algebraic expressions are formed from variables and constants. We use the operations of addition, subtraction, multiplicationand division on the variables and constants to form expressions. For example, the expression 4xy + 7 is formed from the variables x and y and constants 4 and 7. The constant 4 and the variables x and y are multiplied to give the product 4xy and the constant 7 is added to this product to give the expression.
- Expressions are made up of terms. Terms are added to make an expression. For example, the addition of the terms 4xy and 7 gives the expression 4xy + 7.
- A term is a product of factors. The term 4xy in the expression 4xy + 7 is a product of factors x, y and 4. Factors containing variables are said to be algebraic factors.
- The coefficient is the numerical factor in the term. Sometimes anyone factor in a term is called the coefficient of the remaining part of the term.
- Any expression with one or more terms is called a polynomial. Specifically a one term expression is called a monomial; a two-term exp

FINDING THE VALUE OF AN EXPRESSION
We know that the value of an algebraic expression depends on the values of the variables forming the expression. There are a number of situations in which we need to find the value of an expression, such as when we wish to check whether a particular value of a variable satisfies a given equation or not. We find values of expressions, also, when we use formulas from geometry and from everyday mathematics. For example, the area of a square is l 2 , where l is the length of a side of the square. If l = 5 cm., the area is 52 cm2 or 25 cm2 ; if the side is 10 cm, the area is 102 cm2 or 100 cm2 and so on. We shall see more such examples in the next section.
