Because we are using the decimal system which has a base of 10.
This means that there are ten digits (0 to 9) from which all other numbers can be represented. It also means that each digit in a number represents a multiple of a power of 10 which increases by one as you move left. For instance, the number 123 means (3 x 100) + (2 x 101) + (1 x 102).
Once we pass the numbers that we can represent as a multiple of 100 we have to introduce another digit to continue.

The first number must be a nonzero single-digit integer. The exponent must be an integer.
Zero is in the first decimal place of 98. An integer does not have any decimals, however, can be represented with decimals by placing first a decimal point ("dot") after the number and as many zeros as one wishes thereafter. For example, 98 is equal to the following values: (a) 98 (b) 98.0 (c) 98.00 (d) 98.00000000000000 Because the first decimal position is the first one to the right of the decimal point (as represented by examples b, c and d, above), the value is zero.
Divide the smaller number into the bigger one. If the result is an integer, the first number is a factor of the second one.

There are infinite numbers but the first integer or whole number is 100,001

The first 2 digit integer is 10. This is an even number and is therefore the answer.
Yes. If a decimal terminates, then the number can be represented as a fraction because each decimal position represents a specific denominator. (tenths, hundredths, etc). If it repeats, that's an indication of integer division with a remainder, which can be rewritten as an integer over an integer. Non-terminating, not repeating decimals are irrational. However, that is not a practical test, because it would take you an eternity to examine a single irrational number. (It could terminate after the quadrillionth digit, or the first google of digits could repeat.)
Triangular number: An integer of the form (1/2)n(n + 1), where n is a positive integer.12 is not a triangular number. The first few triangular numbers are 1, 3, 6, 10, and 15.
no it depends on if the first number in the equation is bigger or smaller than the second ex. 2-3= -1
IF they are integers, then the first number is a multiple of the second and the second is a factor of the first.
If the integer subtracted is smaller than or equal to the first integer, then the answer is positive. Otherwise, if the integer subtracted is larger, then the answer is negative.
