The answer is a negative or positive integer with one or two digits.
Every integer apart from 0, has two pieces of information: its distance from 0, and its direction from 0. So it has its value and its sign. So you have a positive and negative for each integer. So the digit 2 can be positive 2 or negative 2 for example.

This is a one or two digit positive integer.
The answer is a negative or positive integer with one or two digits.

Every integer apart from 0, has two pieces of information: its distance from 0, and its direction from 0. So it has its value and its sign. So you have a positive and negative for each integer. So the digit 2 can be positive 2 or negative 2 for example.
The first 3 digit integer being a positive multiple of 30 is 120. The final 3 digit integer being a positive multiple of 30 is 990. 990 - 120 = 870. 870 ÷ 30 = 29 But, as 29 is the difference between the two limits and the limits themselves are included then there are 29 + 1 = 30 such numbers.
9797 is the largest two digit prime number.

Positive integers are greater than negative integers. For positive integers: * The integer with more digits is larger. * If two integers have the same length, compare the first digit. If the first digit is the same, compare the second digit, then the third, etc., until you find a difference. In each case, the integer with the larger digit (at the first position where you find a difference) is the larger one.
