Think of this as your "kiasu" (Singlish for "afraid to lose out") guide to acing algebra. ### Algebraic Expressions: The Building Blocks So, what exactly *is* an algebraic expression? Simply put, it's a combination of: * **Terms:** These are the individual parts of the expression, separated by plus (+) or minus (-) signs. * **Coefficients:** The number *in front* of a variable. For example, in the term

3x

, the coefficient is 3. * **Constants:** These are plain old numbers that don't change, like 5, -2, or 3.14159 (that's π, in case you forgot!). * **Variables:** These are letters (like x, y, or z) that represent unknown values. They're the mystery guests of our algebraic party! In this nation's rigorous education framework, parents perform a vital part in directing their kids through milestone evaluations that influence educational trajectories, from the Primary School Leaving Examination (PSLE) which assesses fundamental competencies in areas like numeracy and scientific studies, to the GCE O-Level assessments concentrating on high school mastery in multiple subjects.

2(x + 3)

1. Multiply the term outside the parentheses by each term inside:

2 * x + 2 * 3

2. Simplify:

2x + 6

**Interesting Fact:** The distributive property is like sharing your sweets with your friends. You have to make sure everyone gets a fair share! ### Equations: Expressions with an Equal Sign An equation is simply an algebraic expression with an equal sign (=). It shows that two expressions are equal in value. **Example:**

2x + 3 = 7

The goal when solving equations is to find the value of the variable that makes the equation true.

Common Mistakes and How to Avoid Them

Everyone makes mistakes, especially when dealing with complex equations. But knowing the common pitfalls can help you steer clear of them.

  • Sign Errors: Pay close attention to positive and negative signs, especially when distributing or combining like terms.
  • Order of Operations: Remember PEMDAS/BODMAS (Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction).
  • Incorrect Distribution: Make sure to distribute correctly when multiplying a term by an expression in parentheses.
  • Forgetting to Check: Always, always, always substitute your solution back into the original equation to verify its correctness.

History: The equals sign (=) wasn't always around! Before the 16th century, mathematicians used words or abbreviations to indicate equality. Robert Recorde, a Welsh mathematician, introduced the equals sign in 1557, believing that "noe .2. thynges, can be moare equalle."
