Answer 2

Răspuns:

a)14+16-{8+[7-(2+3)]}=

14+16-[ 8+(7-5)]=

14+16-(8+2)=

30-10=20:

b)[24-(16-2)]-[18-(7+3-2)]=

(24-14)-(18-8)=

10-10=0;

c)120-{27-(5+1)-[13-(10-3)]}=

120-[27-6-(13-7)]=

120-(27-6-6)=

120-15=105;

d)28-(16-2)-{[3+(4-1)]-[5-(3-2)]}=

28-14-[(3+3)-(5-1)]=

14-(6-4)=

14-2=12;

e)24+2•(13•3-15•2):3=

24+ 2•(39-30):3=

24+ 2•9:3=

24+18:3=

24+6=30;

f)16+(135:3-15•3)•625=

16+(45-45l•625=

16+0•625=

16+0=16;

g)132-(5•68-112•3)•31=

132-(340-336)•31=

132-4•31=

132-124=8;
