Multiplying positive numbers always comes out positive, no matter how many there are.  So you can forget about the positive ones.
Every two negative numbers in a multiplication produce a positive.
Another way to say that is:  If the number of negative ones is EVEN,
the answer is positive, and if it's ODD, the answer is negative.
That monster product of eight numbers in problem #12 will be negative,
because there are an odd amount of negative factors in it.

4. Cross multiply (10•6) (15•n) 15n=60 you do the opposite operation so instead of multiply 15•n you divided 15 from n. And what u do on one side u do on both. So divide 15 from 60 and u get 4.
