Why the product of a multiple of ten and a multiple of ten will always have only one zero
I am not entirely sure what you mean; a multiple of 10 can have more than one zeros. For example, 20 x 10 = 200.
The product of zero and any number is always 0.
Yes.
A multiple is a product of that number and any other non-zero integer.
No, but the only exception is if the rational number is zero.
Anytime you multiply a number by zero, the product will always be zero. Thus, whenever a number, regardless of its value, is multiplied by zero, there is only one possible solution: zero.
When you divide zero by anything or multiple anything by zero, the answer will always be zero.
0: The product of 0 and any number, including zero itself. is always zero.
A multiple
If one is zero, then the product is always zero.(Think about it ... you take 279 zero times. How much do you have ?)
a multiple
the product will always end in zero
