Common Mistakes
MISTAKE: Thinking 'unit of hundred' means any number with three digits. | CORRECTION: A 'unit of hundred' specifically refers to the number 100. Numbers like 200, 300 are 'two units of hundred', 'three units of hundred', and so on.
MISTAKE: Confusing 'unit of hundred' with 'hundreds place'. | CORRECTION: 'Hundreds place' is a position in a number (e.g., the '2' in 245 is in the hundreds place). 'Unit of hundred' is the value 100 itself.
MISTAKE: Believing 'one unit of hundred' is the same as 'one hundredth'. | CORRECTION: 'One unit of hundred' means 100. 'One hundredth' means 1/100 or 0.01, which is a very small part of one.
