Just remember to do PEMDAS (Please excuse my dear aunt sally)
Which means the order you solve the equation is by first doing Parenthesis, then Exponents, Multiplication,Division,Addition, then subtraction.

But the answer is - 1262/7 (btw a negative 126/7)

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.
