Work: Calculate the value of equation (250+270)/2*2+(270+260)/2*2+(260+300)/2*3+(300+290)/2*3+(290+320)/2 .
Question type: Mathematical calculation
Solution:
(250+270)/2*2+(270+260)/2*2+(260+300)/2*3+(300+290)/2*3+(290+320)/2
=520/2*2+(270+260)/2*2+(260+300)/2*3+(300+290)/2*3+(290+320)/2
=520/2*2+530/2*2+(260+300)/2*3+(300+290)/2*3+(290+320)/2
=520/2*2+530/2*2+560/2*3+(300+290)/2*3+(290+320)/2
=520/2*2+530/2*2+560/2*3+590/2*3+(290+320)/2
=520/2*2+530/2*2+560/2*3+590/2*3+610/2
=260*2+530/2*2+560/2*3+590/2*3+610/2
=520+530/2*2+560/2*3+590/2*3+610/2
=520+265*2+560/2*3+590/2*3+610/2
=520+530+560/2*3+590/2*3+610/2
=520+530+280*3+590/2*3+610/2
=520+530+840+590/2*3+610/2
=520+530+840+295*3+610/2
=520+530+840+885+610/2
=520+530+840+885+305
=1050+840+885+305
=1890+885+305
=2775+305
=3080
Answer:(250+270)/2*2+(270+260)/2*2+(260+300)/2*3+(300+290)/2*3+(290+320)/2=3080
