Question

90:10+12:3×7+8-3×6:2-2×7+9= 31 como se realiza??​

Answer 1

Respuesta:

$\frac{90}{10} + \frac{12}{3} \times 7 + 8 - 3 \times \frac{6}{2} - 2 \times 7 + 9 = 31 \\ 9 + 4 \times 7 + 8 - 3 \times 3 - 2 \times 7 + 9 = 31 \\ 9 + 28 + 8 - 9 - 14 + 9 = 31 \\ 36 - 14 + 9 = 31 \\ 36 - 5 = 31 \\ 31 = 31$
