How many integers are there between 9 and 100, including 9 and 100?

91 Integers

Step-by-step explanation:

Integers are whole numbers that can either be positive, negative, or zero.

Example would be counting numbers

Basically 100-9=91

so there's 91 integers including 9&100

92 integers

Step-by-step explanation:

You may think 100-91=9 is correct. But because 9 and 100 are included, you have to add 1 to the answer. However, you don't add 2 since 0 is not included into the integers between 1 and 100.
