How many 2 digit numbers can be rounded off to 100?
If you were told to round two digit numbers to the closest 100, you could round everything from 10-99 to the nearest 100, inclusive of 10 and 99. I.e all two-digit numbers round up to 100. This is because "to the nearest hundred" does not mean "up to 100, or down to zero", since "zero" is not in the "hundred's" catagory. i.e you can only round up to 100.This means you have 89 seperate two-digit number which will round up to 100.
Why can't the product of two 2-digit numbers ever be two digit?
The product of two 2-digit numbers cannot be a two-digit number because the smallest two-digit number is 10, and the smallest product of two 2-digit numbers (10 × 10) is 100. Since 100 is a three-digit number, any multiplication of two 2-digit numbers will yield a product that is at least 100 or more. Therefore, the product must always be three digits or greater.
