Variables and Expressions

The value for the expression can be calculated by substituting the value of the variable in the expression. For example, substituting the value of b = 16 in the above expression, we get the expression as 16 + 25, which is equal to 41

While evaluating the expression, we should follow the order of operations using the rule of PEMDAS, which is following the order of Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction from left to right

For a given algebraic expression: 16 + b, 16 is the constant term and b is the variable term. The value of the expression depends on the value of the variable term

The value for the expression can be calculated by substituting the value of the variables in the expression.

For example, substituting the value of x = 4 and y = 2 in the above expression, we get the expression as (5 x 4) + (3 x 2)

For a given algebraic expression: 5x + 3y, 5 and 3 are the constant terms and 'x' and 'y' are the variable terms.

The value of the expression depends on the values of the variable terms used
