Answer 2

Răspuns:

a) 552+[(21,3-7)x2,09]-10-4,7:10=552+(14,3x2,09)-10-4,7:10=552+29,887-10-4,7:10=552+29,887-10-0,47=581,887-10,47=571,417

b) 16,3+(27-0,7)-[16+(2,2-2,2)]:100=16,3+26,3-(16):100=16,3+26,3-16:100=42,6-0,16=42,44

c)11-11-20,02+[17,3-(2,03+3,5)]=0-20,02+(17,3-5,53)=-20,02+11,77=-8,25
