Common Mistakes

MISTAKE: Including 10 itself when asked for numbers less than ten. | CORRECTION: 'Less than ten' means strictly smaller than 10. So, 10 is not included. Think of it as numbers from 9 downwards.

MISTAKE: Confusing 'less than' with 'more than'. | CORRECTION: 'Less than' means smaller, while 'more than' means larger. Always remember the mouth of the comparison symbol (<) points to the smaller number.

MISTAKE: Forgetting that zero is also less than ten. | CORRECTION: Zero (0) is a whole number and is indeed smaller than 10. So, if you have 0 rupees, that's less than ten rupees.
