The expression shown in the image is:

$\left[ (8 - 6) + 10 \right] \div 3 \times 7$

Let's break it down step by step:

1. Simplify inside the parentheses: $8 - 6 = 2$ So, the expression becomes: $\left[ 2 + 10 \right] \div 3 \times 7$

2. Add the numbers inside the brackets: $2 + 10 = 12$ So now the expression is: $12 \div 3 \times 7$

3. Apply the order of operations (PEMDAS/BODMAS): First, divide, then multiply: $12 \div 3 = 4$ Now multiply by 7: $4 \times 7 = 28$

So, the final result is: $28$
