200:2.(540+460):10 = 100 * 1000 : 10 = 10000
200:2.540+460:10 = 100 * 540 + 46 = 54000 + 46 = 54046
200:2.(540+460:10) = 100 * (540 + 46) = 100 * 586 = 58600
1200-200:40·5·5 = 1200 - 5 * 5 * 5 = 1200 - 125 = 1075
1200-200:(40·5)·5 = 1200 - 200:200 * 5 = 1200 - 1 * 5 = 1195
(1200-200:40)·5·5 = (1200 - 5) * 25 = 1195 * 25 = 29875
