Answer 2

Răspuns:

a)25+(13+32)=

=25+45=70

b) (37-9):7+54=

=28:7+54=

=4+54=

=58

c) 54:[6-(13-9)]=

=54:(6-4)=

=54:2=27

d) (3x17)+100:10=

=51+10=61

e) 5x(1200-81:9)=

=5x(1200-9)=

=5x1991=9955

f)32+[2x(101-1)]:10=

=32+(2x100):10=

=32+200:10=

=32+20=52

g) 4+4x[20+6x(25-21)]

=4+4x(20+6x4)

=4+4x(20+24)=

=4+4x44=

=4+176=180

h) 126-[(126:6+109)x(3+3:3)]:10=

=126-[(21+109)x(3+1)]:10=

=126-(130x4):10=

=126-520:10=

=126-52=74
