Answer 2

Răspuns:

*) (3187-185)-3= 3002-3= 2999

c) 54-(13-7)-1079= 54-6-1079= 48-1079= -1031

e) (676-128)-(1156-153-6)=548-(1003-6)=548-997= –449

b) [(18-13)-3189-1502-2]= [5-1687-2] =(-1682-2)=

–1684

a) 3-7-6-0-5-(219-148)= -4-6-0-5-71= -10-0-5-71= -15-71= -56

f) 156-3-45-20-4188-183-2005= 153-45-20-4188= 108-20-4188= 88-4188= -4100
