Simplification of Algebraic Expressions
This lesson covers the definition of algebraic expressions and their components, including terms and coefficients. It explains how to identify like terms, perform arithmetic operations on similar terms, and simplify expressions by inserting or removing brackets.
- 01:36 “Here we deal with alphabets majorly, such as X or Y to represent the unknown values. Here are some examples of algebraic expressions. We have two X plus 10 Y plus one. You can note that it does not have an equal sign. Wh...”

- 06:22 “The same principles apply in algebra. But remember that in algebra, we use a letter of variable to represent a number. For example, a plus a plus a plus a is the same thing as four multiplied by a. In algebra, we normall...”
Translating Word Problems into Equations
The lesson teaches how to translate word sentences into mathematical equations. It covers the use of variables to represent numbers and how to express word problems as algebraic expressions. Students will learn to solve simple equations and check their answers.
- 07:56 “One cup of maize is Sunera. She also sells rice Parkop at double the price of the maize. So one cup of rice is double the price of maize. One cup of rice of one cup is double the price. That is two times the price of mai...”
