They are 3-digit positive integers.

there are 999 - 100 + 1 = 900 positive triple digit positive integers, between 100 and 999.(e.g. there are 102 - 100 + 1 = 3 triple digit integers between 100 and 102,namely 100, 101 and 102.)multiply that by 2 to take in consideration of the negative integers,you have 1800 triple digit integers.

Integers are standalone numbers that can be written without a fraction or decimal point.There are 9 3-digit positive integers N such that N is a multiple of both 7 and 13. They are 182, 273, 364, 455, 546, 637, 728, 819 and 910.

The two-digit positive integers with a tens digit of 3 are: 30 31 32 33 34 35 36 37 38 39

The positive integers up to 4 are: 1, 2, 3, and 4. This is a total of four positive integers.

666 integers.

90 of them.

1 - 3 - 7 - 9 - so ..... 9 * 10 * 4 + 9 * 4 * 6 + 4 * 6 *6 =360+216+104 = 680

There are eight of them.

Three: 1, 2, and 3.

Positive integers are 1, 2, 3, 4, 5, 6 ....

If a digit can be repeated there are 5 x 5 x 5 = 125 possible numbers If a digit cannot be repeated there are 5 x 4 x 3 = 60 possible numbers.

100 to 999 is your range. there are 900 integers in this range. 450 are not divisble by 2 ( the odd ones). 600 are not divisble by 3. half of these are even so only an additional 300 integers are not divisble by 3 alone. so 450 & 300 =750

There are 3168 such numbers.

Four 1-digit integers.

There are an infinite number of positive integers divisible by 3, 5, and 7. This is because there is no limit to numbers and they go on indefinitely in both a positive and a negative direction.

All multiples of 3 have digits that add up to a multiple of 3. There are 333 multiples of 3 between 1 and 1000.
