DEIXE A CONTA POR FAVOR

Answer 1

A) -20+7= -13
=-13+11
=-2
B) -15-5= -20
=-20-7
= -27
C) 14+29= 43
-11-16= -27
=43-27= +16
D)29+33= 62
=62-72
=-10
E) -100-101= -201
182+35= +217
= -201+217
=+16
F) 26-26=0
17+25= +42
=42-42
=0

Answer 2

a) -20+7+11=
-20+7= -13
-13+11= -2

b)-15-5-7 =
-15-5= -20
-20-7= -27

c) +14+29-11-16=
+14+29= +43
+43-11= +32
+32-16= +16


D)+29+33-72=
+29+33= +62
+62-72 = -10



E)+35-100-101+182=
+35-100= -65
-65-101= -166
-166+182= + 16


F)+26-42+17+25-26=
+26-42= -16
-16+17= +1
+1+25=+26
+26-26= 0
