does it really matter
It is not as helpful when multiplying very small numbers because the numbers are going to be very east to answer. That is why estimating is not as helpful when multiplying very small numbers.
Weird
Even numbers are what such numbers are called. If they do have a remainder, they are odd numbers.
Yes.
The infinitely many numbers that leave a remainder when divided by 9. The infinitely many numbers that leave a remainder when divided by 9. The infinitely many numbers that leave a remainder when divided by 9. The infinitely many numbers that leave a remainder when divided by 9.

I would not recommend estimating 1-digit numbers.
First, the word is remainder, not reminder.In any case, none of the followed numbers would give a remainder of 2 since there are no such numbers!First, the word is remainder, not reminder.In any case, none of the followed numbers would give a remainder of 2 since there are no such numbers!First, the word is remainder, not reminder.In any case, none of the followed numbers would give a remainder of 2 since there are no such numbers!First, the word is remainder, not reminder.In any case, none of the followed numbers would give a remainder of 2 since there are no such numbers!
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.
There are different methods for estimating irrational numbers. For numbers like pi or e, there are infinite series which can be used to calculate their value to the required degree of accuracy. There are numerical methods - such as the Newton-Raphson iteration - for estimating roots of numbers.
