12 ÷ 4 - 15 x 10 + 2 = 8
16 ÷ 8 - 5 x 2 + 6 = 9
14 ÷ 10 x 20 - 40 + 34 = 1
If "A" means "subtraction", "B" means "division", "C" means "addition" and "D" means "multiplication", then
294 B 6 A 30 C 31 D 4 = ?
16 x 8 - 4 ÷ 9 + 14 = 37
18 x 12 - 6 ÷ 5 + 4 = 35
If 20 - 10 means 200, 8 / 4 means 12, 6x2 means 4, then
100 - 10 x 1000/ 1000 + 100 x 10 = ?
