Solution n°1
8 - 3 = 5
100 x 7 = 700
700 / 5 = 140
140 + 50 = 190

Solution n°2
50 - 8 = 42
42 x 7 = 294
7 - 3 = 4
294 - 4 = 290
290 - 100 = 190

Solution n°3
8 - 3 = 5
100 / 5 = 20
20 x 7 = 140
140 + 50 = 190

Solution n°4
50 - 8 = 42
42 x 7 = 294
294 - 7 = 287
287 + 3 = 290
290 - 100 = 190

Solution n°5
50 - 7 = 43
43 x 7 = 301
301 - 8 = 293
293 - 3 = 290
290 - 100 = 190
