Question

5.700*0,105-87*1,7+8009:1000-8009*0,001=????????


5867:100+78,55*2,08+51,09*3,4-586,7*0,1=???????

Answer 1

1)5.700*0.105=0.5985
87*1.7=147.9
0.5985-147.9=-147.3015
8009:1000=8,009
-147.3015=(-8.009)=-155,3105
8009*0.001=8,009
-155.3105-8.009=163,3195

2) 5867:100=58.67
78.55*2,08=163,384
58,67+163,384=222,054
51,09*3,4=173,706
222,054+173,706=395,76
586,7*0.1=58,67
395,76-58,67=337,09
