5*5*4*4 = 400

There are 26 different letters that can be chosen for each letter. There are 10 different numbers that can be chosen for each number. Since each of the numbers/digits that can be chosen for each of the six "spots" are independent events, we can multiply these combinations using the multiplicative rule of probability.combinations = (# of different digits) * (# of different digits) * (# of different digits) * (# of different letters) * (# of different letters) * (# of different letters) = 10 * 10 * 10 * 26 * 26 * 26 = 103 * 263 = 1000 * 17576 = 17,576,000 different combinations.

135 + 246 = 381 You can swap the digits in the hundreds' place between the two numbers, the tens' place and the units' place, for example, 145 + 236 (tens')

With base one million, you can create one nonillion different numbers; using the traditional decimal (base ten) system, you can form 100 thousand different numbers.
25 digit numbers would be septillions.
100,000.00 either 5 or 7, depending if you count the change places
200,000. Since the number 200 is in the hundreds, it will be 3 digits long. A number in the thousands has at least 4 digits, and up to 6. The number one thousand is written like this: 1,000. Putting the number 1 in the thousands requires adding 3 zeros to the end of it, so writing the number 200 in the thousands would require the same strategy. Therefore, you'd get to your answer: 200,000.
89,999 different numbers i guess
All of them. We normally count in decimal numbers and therefore all digits in decimal numbers must be less than ten.
ten
There should be 3 digits to the right of the "thousand" part - therefore, you have 880,064.
3,612,345,678
5040 different 4 digit numbers can be formed with the digits 123456789. This is assuming that no digits are repeated with each combination.
