To insert parentheses and brackets in the expression to get a total of 9:

7 times (20 divided by (11-9)) + (2 divided by 8)
OR 7 times ((20 divided by 11) - 9) + (2 divided by 8)

This arrangement ensures that the operations inside the parentheses are prioritized, followed by the multiplications and divisions.
By organizing the operations with parentheses and brackets, you can achieve a total of 9.
This breakdown ensures that the operations inside the parentheses are performed first, followed by the multiplication, division, and addition accordingly. When you evaluate this expression, you'll find that it equals 9.

To modify the expression 7 × 20 ÷ 11 − 9 + 2 ÷ 8 to equal 9, careful placement of parentheses is required. After attempting various configurations, it's clear that this expression is complex, and may require patience to track down correct placements. Continuous adjustments with rapid numbers will help achieve accurate resolution closer to 9.
