What is the predecessor of the smallest 2-digit prime number?
Answers
Answer:
prime numbers : 2, 3, 5, 7, 11, 13, 17, 19, etc.
smallest 2 digit prime number from the above is 11
predecessor of 11 is 10
Therefore, your answer is 10.

Practical Answer
When talking about math “smallest” generally means the lowest magnitude (absolute value), that is; the closest to zero. Likewise, “two digit number “ generally refers to an integer, that is a whole number (no decimals or fractions). By these rules the smallest two digit number is 10.
Not So Practical…
However, in more broad terms; smallest could mean mean lowest value and two digit number could be any number consisting of two digits. In this case it would be -99.
If “smallest” were to hold its connotation as lowest magnitude, and “two digit number” be any number composed of any two digits, then the smallest two digit number would be either 00 or .01 (depending on who you ask, some people argue that zero is not a number, but rather a place holder.)
Another way to go about this is considering scientific notation. 1000 in scientific notation may be written as 1 x 10^3 or as 1 E3. They both mean the same thing, the latter is used by calculators. In this case the smallest two digit number is either, -9 E9 (which equals -9,000,000,000) with “smallest” defined as the lowest value. Or 1 E-9 (which equals 0.000000001) with “smallest defined as the lowest magnitude and using numbers other than zero.
There are some other crazy ways to go about this, like putting the number in the from of an equation (but then it’s not technically a number).
I hope this helps!
