-ve + -ve=-ve
-ve + +ve this depends on size of figures e.g -5 + 3=-2 but -5 + 6=+1
-ve - -ve= again depends on size of figures but - -ve is same as adding +ve number to first -ve number
-ve - +ve= -ve always
-ve x -ve= +ve always
-ve x +ve= -ve always
hope you understand

a + a = a ; site an example 3 + 2= 5 adding at the same sign will give u the sum and copy the common sign
-a + a = (-3)+2=-1 and 2+(-3)=-1 adding a different sign will give u a subtaction and copy the sign which has a bigger value
(-a)-(-a)=(-a)+a site an example(-3)-(-2)= (-3)+2=-1 copy the first given value and change the minus sign into plus sign then change the second value to the opposite sign

(-a)-a=(-a)+(-a) copy the first given and change the minus sign into plus sign then change the second value to the opposite sign
(-a)*(-a)=a; multiply the same sign will give as positive value
(-a)*a=(-a); multiply unlike sign will give you negative value
