Answer 1

2-4 = 2-4=-2-5=-7+8= -1
6-7=-1+4=3-3=0
5+8=13-9=4-6= -2
-4-9=-13+6=-7+2= -5
-3-5=-8+7=-1+7= 6
2-4=-2-8=-10-2=-12-5= -17

Answer 2

Respuesta:2 – 4 – 5 + 8 = – 2 – 5 + 8 = – 7 + 8 = +1

6 – 7 + 4 – 3 =  6+4 = 10-7 = 3-3 = 0  

5 + 8 – 9 – 6 = 5+8 = 13-9 = 4-6 = -2  

–4 – 9 + 6 + 2 = -4-9 = -13+6 = -7+2 = -5  

–3 – 5 + 7 + 7 = -3-5 = -8+7 = -1+7 = 6  

–4 – 8 – 2 – 5 = -4-8 = -12-2 = -14-5 = -19
