Question

coloque na forma simplificada e calcule A: (-2)+(-3)+(+2) B: (-3)+(-3)+(-5) C: (+1)+(+8)+(-2) D: (+5)+(-8)+(-1) E: (-6)+(-2)+(+1) F: (-8)+(+6)+(-2) G: (-7)+6+(-3) H: 6+(-6)+(-7) I:-6+(+9)+(-4) J: (-4)+2+4+(+1)

Answer 1

A:
= (-2)+(-3)+(+2)
= - 2 - 3 + 2
= - 5 + 2
= - 3

****************************
B:
= (- 3) + (- 3) + (- 5)
= - 3 - 3 - 5
= - 6 - 5
= - 11

*****************************
C:
= (+1) + (+ 8) + (- 2)
= 1 + 8 - 2
= 9 - 2
= 7

*********************************
D:
= (+ 5) + (- 8) + (- 1)
= 5 - 8 - 1
= 5 - 9
= - 4

****************************
E:
= (- 6) + (- 2) + (+ 1)
= - 6 - 2  + 1
= - 8 + 1
= - 7
**************************
F:
= (-8)+(+6)+(-2)
= - 8 + 6 - 2
= - 2 - 2
= - 4

************************
G:
= (- 7) + 6 + (- 3)
= - 7 + 6 - 3
=  - 1 - 3
= - 4

****************************
H:
= 6+(-6)+(-7)
= 6 - 6 - 7
= 0 - 7
= - 7

**************************
I:
= - 6 + (+9) + (- 4)
= - 6 + 9 - 4
= 3 - 4
= - 1

******************************
J:
= (-4)+2+4+(+1)
= - 4 + 6 + 1
= - 4 + 7
= 3

Answer 2

Olá

Vamos lá,

coloque na forma simplificada e calcule
A: (-2)+(-3)+(+2)
=-2-3+2
=-5+2
=-3

B: (-3)+(-3)+(-5)
=-3-3-5
=-6-5
=-11

C: (+1)+(+8)+(-2)
= 1 +8-2
=9-2
=7

D: (+5)+(-8)+(-1)
=5-8-1
=-3-1
=-4

E: (-6)+(-2)+(+1)
=-6-2+1
=-8+1
=-7

F: (-8)+(+6)+(-2)
=-8+6-2
=-2-2
=-4

G: (-7)+6+(-3)
=-7+6-3
=-1-3
=-4

H: 6+(-6)+(-7)
=+6-6-7
=-7

I:-6+(+9)+(-4)
=-6+9-4
=3-4
=-1

J: (-4)+2+4+(+1)
=-4+2+4+1
=-2+4+1
=2+1
=3
