Whole Numbers (P6) Practice
Master PSLE-level whole-number problems: order of operations, rounding large numbers, digit-arrangement problems, and multi-step word problems. These appear throughout the exam paper.
Common Mistakes to Avoid
Applying operations in the wrong order (not following BODMAS)
Confusing 'smallest' with 'leading zero not allowed' in digit arrangement
Rounding to the wrong place value under time pressure
Practice Questions

Express 4.05 million as a whole number.
Using each digit 0, 2, 5, 7, 8 exactly once, form the smallest 5-digit odd number.

Common Questions
What is the most common BODMAS mistake in PSLE?
Treating addition before multiplication. For example, in '3 + 4 Γ 2', many students compute (3 + 4) Γ 2 = 14 instead of the correct 3 + 8 = 11. Always identify the multiplication/division first, then handle addition/subtraction.
How do I convert millions to whole numbers quickly?
Shift the decimal point 6 places to the right. For example: 0.02 million = 20 000 (shift decimal 6 right); 2.5 million = 2 500 000. Conversely, to convert a whole number to millions, shift 6 places left.
