I believe that the numbers One and Nine fit the bill as they would be 1x9= 9 and 1+9=10.
504 = 8 x 9 x 7
A one digit multiplication problem is one in which the numerals being multiplied have only one digit. Examples would include: 6x2 or 5x3 or 7x4 or 1x8. (These are just a few examples. The list of all the possible one digit multiplication problems would be very long.) A two digit multiplication problem is one in which the numbers being multiplied have two digits. Examples would include: 12x43 or 16x21 or 75x23.
Okey-dokey. I have no idea what the heck you are asking. 'What numbers do you find in the ones digit for the number 2?' Well, the number 2 is only one digit, so the answer would be, '2.' DUH!
The ratio of the number of one-digit prime numbers to the number of one-digit composite numbers is one to one. The one-digit prime numbers are 2, 3, 5, and 7. The one-digit composite numbers are 4, 6, 8, and 9. Therefor, the ratio is 4:4, which simplifies to 1:1.
All numbers can be multiplied that way. A prime number is one that can only be divided by one and itself.
One, two, and three.
It means that you are talking about numbers that have more than one digit.
One can easily find the units digit by looking for a pattern. For numbers with large powers, they will have a pattern that keeps repeating like a cycle. Depending on the multiple of the power, the pattern can be compared to find the units digit.
There are four of each.
