100× (371+235)=
100×(984-532)=
100×(708+967=
100×(823-154)=​

Answer 1

Răspuns:

(25+13)*10=38*10=380

25*10+13*10=250+130=280

(76-18)*10=58*10=580

76*10-18*10=760-180=580

(83+15)*10=98*10=980

83*10+15*10=830+150=980

(91-64)*10=27*10=270

91*10-64*10=910-640=270

100*(371+235)=100*606=60600

100*371+100*235=37100+23500=60600

100*(984-532)=100*452=45200

100*(708+967)=100*1675=167500

100*708+100*967=70800+96700=167500

100*(823-154)=100*669=66900

100*823-100*154=82300-15400=66900
