Question

Poate cineva sa ma ajute astea 2?

b= +8–7–9–[–4+2–1+3–(–1+3–
4+6)]


c= (+2–6–4+5–3–7+1+6)–(+1–8 –7+9+3–9+5+4) ​

Answer 1

Răspuns:

b= 8-7-9-[(-4)+2-1+3-4]

b= 8-7-9-4

b= -12

c= -6-(-2)

c= -4

Explicație pas cu pas:

Answer 2

Răspuns:

b= +8 - 7 - 9 [ - 4 +2-1+3-( 2 + 2)]

b= +8-7-9-(-4+2-1+3-4)

b=+8-7-9-(-2+2-4)

b=+8-7-9-4

b=1-13

b=-12

c=(2-6-4+5-3-7+1+6)-(1-8-7+9+3-9+5+4)

c=(-8+2)-(-14+12)

c= - 6 +2

c= - 4
