determina ordinea efectuarii operatiilor, apoi calculeaza (325+124)-(186+95),(842-428)+(330-305),(325+85)-206-96,841-509-200+53 ,26x(10-3) , 54:(9:3) , 34+(17+2)x7 , (28+52):(2+18) , 3x14+146 , 245-4x25, 3x16+10x18 , 225:3+423:9 , 1x40+404 , 404-(40:4+4) , 4x2x30:20 , 200:5:4 , 303:3+303 , 125x3+125x2 .

Answer 1

(325+124)-(186+95)=449-281=168
(842-428)+(330-305)=414+25=439
(325+85)-206-96=410-206-96=204-96=108
841-509-200+53=332-200+52=132+52=184
26x(10-3)=26x7=182
54:(9:3)=54:3=18
34+(17+2)x7=34+19x7=34+133=167
(28+52):(2+18)=80:20=4
 3x14+146=42+146=188
245-4x25=245-100=145
3x16+10x18=48+180=228
225:3+423:9=75+47=122
1x40+404=40+404=444
404-(40:4+4)=404-(10+4)=404-14=390
4x2x30:20=8x30:20=240:20=12
200:5:4=40:4=10
303:3+303=101+303=404
125x3+125x2=375+250=625
