Илюха отвечает:
((140 – 80)/4)*5 = 75
(60/4)*5 = 75
15 * 5 = 75
75 = 75.
(140 – (80/4)) * 5 = 600
(140 – 20) * 5 = 600
120 * 5 = 666
600 = 600.
140 – (80/(4 * 5)) = 136
140 – 80/20 = 136
140 – 4 = 136
136 = 136.
8 * 30 – 30/(3 * 5) = 238
240 – 30/15 = 238
240 – 2 = 238
238 = 238.
8 * (30 – 30)/3 * 5 = 0
8 * 0/3 * 5 = 0
0 = 0.
((8 * 30) – 30)/3) * 5 = 350
((240 – 30)/3 * 5 = 350
(210/3) * 5 = 350
70 * 5 = 350
350 = 350.
