Explicación paso a paso:
LA MULTIPLICACION SIEMPRE ES PRIMERO
* 3 X 4 + 5 - 2 = 12 + 5 -2 = 17 - 2 = 15
* 2 + 6 X 3 - 9 = 2 + 18 - 9 = 20 - 9 = 11
* 56 - 35 + 3 X 5 = 56 - 35 + 15 = 21 + 15 = 36
* 2 X 3 + 7 X 3 = 6 + 21 = 27
* 4 X 5 + 6 - 15 = 20 + 6 - 15 = 26 - 15 = 9
* 9 X 3 + 6 X 4 = 27 + 24 = 51
* 7 X 9 + 5 - 35 = 63 + 5 - 35 = 68 -35 = 33
* 6 + 8 X 3 - 7 = 6 + 24 - 7 = 30 - 7 = 23
* 14 - 7 + 3 X 9 = 14 - 7 + 27 = 7 + 27 = 34
* 12 X 3 - 5 + 3 = 36 -5 +3 = 31 +3 =34
* 6 + 3 X 5 + 8 - 9 = 6 + 15 + 8 -9 = 21 +8 -9 = 29 - 9 = 20
* 4 X 5 + 6 X 3 = 20 + 18 = 38
*6 X 7 - 3 X 7 = 42 - 21 = 21
* 8 X 6 - 40 +35 = 48 - 40 + 35 = 8 + 35 = 43
