Question

Quien me ayuda porfa es urgente

Answer 1

Respuesta:

+5 - (-6) = 5+6= 11

+5 - (+6) = +5-6= -1

-5 - (-6) = -5+6 = +1

-5 - (+6) = -5-6= -11

-3 - (+9) = -3-9= -12

-3 - (-9) = -3+9= 6

+3 - (+9) = +3-9= -6

+3 - (-9) = +3+9= 12

(+8)-(+9)+(-7)= +8-9-7= -1-7= -8

(-12)- (-3) + (+5)= -12+3+5= -9+5= -4

(+9)+(-13)-(-21)= +9-13+21= -4+21= 17

(-17)+(+5)-(+20)= -17+5-20= -12-20= -32

-7-(-12)-(+3)= -7+12-3= 5-3= 2

-5-(+11)-(-20)= -5-11+20= -16+20= 4

9-[(-5)-(+7)]= 9+5+7 = 21 ( Si no entiendes este problema, sólo utilice la ley de signos, en este caso +.-= -)

-7-[(-3) - (-9)]= -7+3+9= -4+9= 5

-11-[(+6)-(+4)] -11-6+4= -17+4= -13

+8- [(+5)-(-9)] = +8-5-9 = 3-9= -6

(+4) +[(+3)+(-7)]+(+1)= +4+3-7+1 = +7-7+1 = 0+1= 1

-(-3)+{(-5)-[(+8)+(-10)}= +3-5-8+10= -2-8+10= -10+10 = 0
