Interesting Fact: The word "algebra" comes from the Arabic word "al-jabr," which means "the reunion of broken parts." This refers to the process of rearranging terms in an equation to solve for an unknown.

Diving Deeper: Algebraic Expressions and Equations

Let's break down some key aspects of algebraic expressions and equations, especially relevant for secondary 2 math:

  • Simplifying Expressions: This involves combining like terms to make an expression easier to work with. For example, 3x + 2y + 5x - y simplifies to 8x + y.
  • Expanding Expressions: This involves multiplying out terms within parentheses. For example, 2(x + 3) expands to 2x + 6.
  • Solving Linear Equations: These are equations where the highest power of the variable is 1. For example, 2x + 5 = 11.

  • Solving Simultaneous Equations: These are sets of two or more equations with two or more variables. The goal is to find the values of the variables that satisfy all equations simultaneously. For example:

    • x + y = 5
    • x - y = 1

    You can use methods like substitution or elimination to solve these.
