Algebraic expressions are used in many application areas. In this paper, we propose a novel code optimization technique for algebraic expression. We used two techniques to reduce cost with respect to time. Experimental results are obtained by comparing optimization ratio of existing optimization approach with the proposed approach. Therefore, we used simple substitution method to solve algebraic problem and standard optimization technique and calculate the results that how both techniques reduce the complexity of Algebraic expression. The results show that cost of Algebraic expression using substitution and cost of optimize algebraic expression without substitution results is less than the original optimize Algebraic expression.
