b) (-88):(-4)-125:(-5) -380;
c) {6-[282.(-1)-(44:11-18)]}-644;
d) 25 :(-5)- {42 +3.[6-(3.5+11)]}.​

Answer 1

Explicație pas cu pas:

a) -12-14+2010=-26+2010=1994

b) 22+25-380=47-380=-333

c) {6-[-282-(4-18)]}-644=[6-(-282+14)]-644=(6+268)-644=274-644=-370

d)-5-{42+3[6-(15+11)]}=-5-{42+3[6-26)]}=-5-{42+3•(-20)}=-5-{42-60}=-5-(-18)=-5+18=13
