She also bought a kilo of fish, and other ingredients that costs 120 pesos. How much did she spend? Real life scenarios like this represents evaluating algebraic expressions. Getting the total amount of what you spend in grocery is like adding polynomials. Knowing how much of the money is left after payment resembles subtracting polynomials. In the next part of this module, you will learn more about evaluating, adding, and subtracting polynomials.​
