Subtopic: Estimation Techniques

Estimation is a powerful tool for checking the reasonableness of your answers. Learn to round numbers and approximate calculations to get a rough estimate of the answer. This can help you identify if you've made a significant error with your calculator.

Subtopic: Formula Memorization

While calculators can perform calculations, they can't replace the need to memorize key formulas and concepts. Make sure you have a solid understanding of the formulas relevant to your syllabus. Flashcards and regular practice can help with memorization.

History: The word "calculate" comes from the Latin word "calculus," which means "small stone." Ancient Romans used pebbles to perform calculations!

So, remember, the calculator is a tool, not a crutch. Master the fundamentals, practice problem-solving strategies, and use your calculator wisely. With the right approach and maybe some good ol' singapore secondary 3 math tuition, your child will be well-prepared to ace those secondary 3 math exams! Don't be *blur like sotong* during the exam, okay?
