That's because it is defined to be that way. This definition is quite logical; consider the following sequence:
3 x 10 = 30
2 x 10 = 20
1 x 10 = 10
0 x 10 = 0
-1 x 10 = ???
What number would you expect to replace the question marks? Look for a pattern. The numbers in the first column decrease by one at a time; the numbers in the last column decrease by ten at a time in this example, so you would expect the next number to be -10.
Defining multiplication this way makes many mathematical laws consistent, not only for positive numbers, but only for negative numbers - for example, the distributive law.

It could equal both a negagtive number or a positive number. To get a definite positive or negative you times or divide.
