# AE01 Introduction to Algebraic Expressions

This is the first part of our series on algebraic expressions. In this video, we will learn how to generalize patterns to understand the meaning of algebraic expressions. Watch the Taglish math tutorial video above and then answer the exercises below. The complete video playlist of the Sipnayan tutorials on algebraic expressions can be found here.
