If you would like to evaluate 6 [5 (3 - 9) - 1] + 2 / 7 (8 - 2) + 4, you can calculate this using the following steps:

6 [5 (3 - 9) - 1] + 2 / 7 (8 - 2) + 4 = 6 [5 (-6) - 1] + 2/7 6 +  4 = 6 [- 30 - 1] + 12/7 + 4 = 6 * [- 31] + 12/7 + 4 = - 186 + 12/7 + 4 = - 182 + 12/7 = - 1274/7 + 12/7 = - 1262/7

The correct result would be - 1262/7.
