Real-Life Example: The Hawker Stall Problem

Let's say a hawker stall sells chicken rice and nasi lemak. Chicken rice costs \$3, and nasi lemak costs \$4. One day, the stall earned \$150. If they sold 20 plates of chicken rice, how many plates of nasi lemak did they sell?

Here's how to set up the equation:

  • Let 'n' be the number of nasi lemak plates sold.
  • The total earnings from chicken rice are 20 * \$3 = \$60.
  • The total earnings from nasi lemak are n * \$4 = \$4n.
  • The total earnings are \$60 + \$4n = \$150.

Now you can solve for 'n':

  • \$4n = \$150 - \$60
  • \$4n = \$90
  • n = 22.5

Wait a minute! You can't sell half a plate of nasi lemak! This highlights the importance of checking your answer and making sure it makes sense in the real world. In this case, there might be a mistake in the problem, or we need to consider that the hawker might have given a discount on one of the plates.

Misunderstanding Variables

Students often struggle with the concept of variables, treating them as labels instead of unknown quantities. This leads to incorrect equation setups, such as assigning 'a' to represent apples instead of the *number* of apples. Clear understanding of variables is crucial for accurate algebraic representation.

Incorrectly Translating Word Problems

A common error is misinterpreting the language of word problems. Students may struggle to identify key phrases like "more than" or "less than," leading to incorrect mathematical operations in the equation. Careful reading and understanding of the problem's context is essential.

Ignoring Order of Operations

Failing to adhere to the order of operations (PEMDAS/BODMAS) when setting up equations can result in incorrect expressions. This is especially true when dealing with multiple operations within a single equation. Always prioritize parentheses, exponents, multiplication/division, and addition/subtraction.

Forgetting to Distribute

When an expression involves multiplication over a sum or difference within parentheses, students sometimes forget to distribute the multiplication to each term. This oversight leads to an incomplete and incorrect equation. Remember to multiply the term outside the parentheses by every term inside.

Not Defining the Unknown

Before setting up an equation, it's vital to clearly define what the variable represents. Students may jump into forming equations without identifying the unknown they're trying to solve for. This lack of clarity often leads to confusion and incorrect equation structures.
