If multiplying 3 digit numbers with 2 digit numbers. For example; 345 x 92=
First you will start with 2 by multiplying it by 5 then carry the 1 above the 4 then multiply the "2" with 4 then add the number on-top of the 4 which is 1 and it will give you 9. 4 x 2= 8+1=9. Then times the 2 by 3 which is 6. That is not your answer, yet. 690 plus the amount you get by multiplying 9 by every number, 5 then carry the number, 4 times 9, plus the number above it, then carry the 3 on top of the 3. Then add your total to 690 or what ever your equation is.
There are no such numbers.
You multiply the one digit number on the bottom to every number on the top starting at the right and so on with every other number on the bottom.
4 options for the first digit, 3 options for the second digit, 2 options for the third digit. Multiply the number of options together, and you find how many 3-digit numbers you can get.
A 3 or 4 digit number.
If you multiply 2*9, you get 18. Multiply that by 10 to get a three digit number, and you get 180.
first digit time second digit and second digit times first digit then repeat

you multiply 3 digit numbers by killing yourself and giving away body parts.

If this is a homework assignment, please consider trying it yourself first, otherwise the value of the reinforcement to the lesson offered by the homework will be lost on you.There are 60 possibilities that can be made for a three digit number using the numbers 2 4 6 8 and 9. (5 choices for the first digit, 4 choices for the second digit, and 3 choices for the third digit - multiply 5, 4, and 3, and you get 60.)To determine how many of these three digit numbers are smaller than 500, consider that, given 2 4 6 8 and 9, the first digit would have to be 2 or 4. That gives 2 choices for the first digit, 4 choices for the second digit, and 3 choices for the third digit. Multiply 2, 4, and 3, and you get 24.
If you multiply 2*9, you get 18. Multiply that by 10 to get a three digit number, and you get 180.
