Syntax Savvy

Syntax refers to the specific rules for how expressions are written on a calculator. Different calculators may have slightly different syntax requirements. For instance, some calculators require you to enter the root index before the root symbol (e.g., 3√8 for the cube root of 8), while others might work the other way around. Failure to adhere to the correct syntax will result in a syntax error or, worse, an incorrect calculation without any error message. This is where familiarity with your specific calculator model is key – "kiasu" (afraid to lose) students practice beforehand!

Fraction Fumbles

Fractions can be tricky on a calculator. Some calculators have a dedicated fraction button, while others require you to use division. When dealing with mixed numbers, be especially careful. If your calculator doesn't have a direct way to input mixed numbers, convert them to improper fractions before entering them. For example, 2 1/2 should be converted to 5/2. Incorrectly entering fractions is a common source of error, especially when questions from the secondary 4 math syllabus Singapore involve complex fractional expressions. Let's not "kancheong spider" (get anxious) over fractions!

Function Faux

Many calculators have built-in functions like sine, cosine, tangent, logarithms, and exponentials. Ensure you understand how to use these functions correctly. A common mistake is forgetting to set the calculator to the correct angle mode (degrees or radians) when working with trigonometric functions. Always double-check the mode setting before performing any trigonometric calculations. Also, be mindful of the syntax for entering function arguments – some calculators require parentheses around the argument (e.g., sin(30)), while others do not. Think of these functions as specialized tools – you need to know how to use them properly to get the job done!
