adding 10?
3
to multiply a number by 10, all you have to do is add zeros at the end of the number. Below are examples: 10*1=10 10*10=100 10*100=1000
Choose any number for the first number. Subtract 10 minus the number you chose to get the second number.

You are 9.
No. The factors of 10 other than 10 itself are 1, 2, and 5. These add up to 8, not 10.
The answer is 5,950. Note that when adding a number to itself n times, you simply multiply the number by n. In this case, n is 10, so 595 x 10 = 5950.
The prime number less than 10 that, when added to either 10 or 20, results in a prime number is 3. When you add 10 to 3, you get 13, which is a prime number. Similarly, when you add 20 to 3, you get 23, which is also a prime number.
7 and 3
Just add a zero after the number. 123 x 10 = 1230
The number is 10 because (5*10)+14 = 64
it is 10 times larger (of the number that was multiplied by 10 or added a zero at the end)
