Unmasking Algebra's Tricky Twins: Common Mistakes in O-Level Math

**

Imagine algebra as a bustling hawker centre, each equation a diverse food stall waiting to be sampled. But beware, not all dishes are as they seem. Today, we're exposing algebra's 'tricky twins'—common mistakes that can trip up even the sharpest calculators. So, grab your pens and let's dive in!

**

Mistake 1: The Great Distraction - Misplaced Brackets

**

Picture this: You're standing in line for your favourite char kway teow, but the auntie mixes up your order with the person behind you. Chaos ensues, right? Brackets in algebra are like that auntie—they group operations together, dictating the order in which calculations are done. Misplacing them can lead to disastrous mix-ups!

For instance, consider 2 + 3 × 4. Without brackets, it's like the auntie serving the wrong noodles. The multiplication should come first, so the correct answer is 14, not 20. Remember, PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) is your order-keeping lifesaver!

**

Mistake 2: The Copycat - Careless Substitution

**

Now, imagine you're at a food court, and the stalls are numbered. If you order from stall 1, you expect a certain dish. But what if the stall assistant mistakes your order and serves you something from stall 10 instead? That's careless substitution for you!

In algebra, variables represent values. If you replace a variable with a value, ensure you're using the correct one. For example, if x = 3, don't accidentally use x = 5 in your calculations. Always double-check your substitutions to avoid serving up the wrong answer!

**

Mistake 3: The Mix-Up - Incorrect Order of Operations

**

Back to our food stall analogy, what if the auntie serves your satay before your rice, even though you asked for the rice first? That's an order of operations mix-up! In algebra, operations (like multiplication and division) must be done before addition and subtraction.
