Common Mistakes

MISTAKE: Including the number 5 itself when asked for numbers 'less than 5'. For example, saying 5 is less than 5. | CORRECTION: 'Less than' means strictly smaller. 5 is equal to 5, not less than it. Always exclude the number you are comparing against.

MISTAKE: Confusing 'less than' with 'greater than'. For example, thinking 7 is less than 5. | CORRECTION: Remember 'less than' means smaller. Think of a number line: numbers to the left are smaller.
