for any integer a what is (-1) x a equal to?
when we multiply any positive number with -1 , we will get the same number with negative sign and if negative then + sign with the same number
- -1*-5=5
we got the positive number by multiplication of -1 with negative number (i.e : 5)
- -1*5=-5
we got the negative number by multiplication of -1 with positive number (i.e : -5)
