3 + 6 + 4 8 (8 + 3/4) - 7 - 5/6 = 3 + 6 + 4 8 (32/4 + 3/4) - 7 - 5/6= 3 + 6 + 4 8 (35/4) - 7 - 5/6= 3 + 6 + 4 8 8.75 - 7 - 5/6= 3 + 6 + 35 - 7 - 5/6= 9 + 28 - 7 - 5/6= 1 + 28 - 5/6= 29 - 5/6= 29 - 0.83= 28.17

3 + 6 + 4 8 (8 + 3/4) - 7 - 5/6 = 3 + 6 + 4 8 (32/4 + 3/4) - 7 - 5/6
= 3 + 6 + 4 8 (35/4) - 7 - 5/6
= 3 + 6 + 4 8 8.75 - 7 - 5/6
= 3 + 6 + 35 - 7 - 5/6
= 9 + 28 - 7 - 5/6
= 1 + 28 - 5/6
= 29 - 5/6
= 29 - 0.83
= 28.17
