(-3)-5-(2+7)+(-3)
= - 3 - 5 - 2 - 7 - 3
= - 20
(-7)-(7-(-4))+(-5)-8
= - 7 - 7 + 4 - 5 - 8
= - 7 - 7 - 5 - 8 + 4
= - 27 + 4
= - 23
6-9+4
= 6 - 9 + 4
= 6 + 4 - 9
= 10 - 9
= 1
(-6)+9-4
= - 6 + 9 - 4
= - 6 - 4 + 9
= - 10 + 9
= - 1
6-9-4
= 6 - 9 - 4
= 6 - 13
= - 7
(-6)-9-4
= - 6 - 9 - 4
= - 19
(-4)-8+12
= - 4 - 8 + 12
= - 12 + 12
= 0
