This seems like an odd definition but we’ll need it for the definition of a function (which is the main topic of this section) however, before we actually give the definition of a function let’s see if we can get a handle on just what a relation is. Ccssmathcontent6eea2c evaluate expressions at specific values of their variables include expressions that arise from formulas used in real-world problems perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (order of operations. Menu pre-algebra / introducing algebra / evaluate expressions a variable is a letter, for example x, y or z, that represents an unspecified number $$6+x=12$$ to evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations in the example above, the variable x is equal to 6 since 6. We have learned that, in in an algebraic expression, letters can stand for numbers when we substitute a specific value for each variable, and then perform the operations, it's called evaluating the expression let's evaluate the expression 3y + 2y when 5 = y.
