a)-8-7-(5+4)-3=
b) 7+2+(8-3)-(5-2) =
a
c) -(4-3)+(5-2)-(7+3) =
d) -3-4-(3-6)-(8+5) =
e) -(3-(8-6)-(5+4)]=​

Answer 1

a) -8-7-(5+4)-3
= -8-7-5-4-3
=-8-7-5-7
=-14-8-5
=-14-13
=-27
b) 7+2+(8-3)-(5-2)
= 7+2+8-3-5+2
= 9+5-5+2
= 9+2
= 11
c) -(4-3)+(5-2)-(7+3)
= -4+3+5-2-7-3
= -4+5-2-7
= 1-2-7
= 1-9
=-8
d) -3-4-(3-6)-(8+5)
=-3-4-3+6-8-5
= -6+6-4-13
= -17
e) -(3-(8-6)-(5+4))
= -3+(8-6)+(5+4)
= -3+8-6+5+4
= -9+9+8
=8
