Integers are whole numbers (including zero) and their negatives.
I = {..., -2, -1, 0, 1, 2, ...}
The positive integers are restricted to just:
P = {1, 2, 3, ...}
The two digit numbers in this set begin at 10 and end at 99. To count them, simply subtract and add one:
99 - 10 + 1 = 90.
Or, count starting at 11 and you'll end up with 89, then add one more for 10 to get 90.

What else can I help you with?
What will be the sign of the product if we multiply 90 negative integers and 9 positive integers?
The product of any number of negative integers is positive if there is an even count of them, and negative if there is an odd count. Since 90 is an even number, the product of the 90 negative integers will be positive. When this positive product is multiplied by the 9 positive integers, the overall product remains positive. Therefore, the sign of the product will be positive.
How many two-digit positive integers are there?
90
What is the number of two digit positive integers?
There is no such thing as "intergers".The complete list of two-digit positive whole numbers lists 90 of them.
What five integers between 1-100 have the most positive integers?
60, 72, 84, 90 and 96 have 12 factors.
What goes into 279 that also goes into 90?
The positive integers are 1, 3 and 9.
What are non positive integers?
Non-positive integers are zero and the negative integers.
What are the greatest factors of 75 and 90?
The greatest factors of any positive integers are the numbers themselves. The greatest common factor of 75 and 90 is 15.
When the negative integers the positive integers and 0 are combined the integers are formed?
Negative integers, zero and the positive integers, together form the set of integers.
What is the least common factor for 28 and 90?
The least common factor of any set of positive integers is 1.
Are all integers positive?
The set of integers includes negative integers as well as positive integers. It also includes the number zero which is neither negative nor positive.
Are 0 0.25 and 2.6 positive integers?
No, none of them are positive integers.
What is the LCF of 90 and 72?
The least common factor of any two positive integers is 1.
