Use only the following numbers only once each: 

2, 3, 7, 8, 50 and 75 

to obtain a result of 812

By using the following mathematical functions in any order:

Addition 
Subtraction 
Multiplication 
Division 


To achieve a result of 812 using the numbers 2, 3, 7, 8, 50, and 75 with addition, subtraction, multiplication, and division, we can perform the following operations:

\[
(75 \times 8) + (50 \times (7 + 2)) + 3 = 812
\]

Let's break it down step by step:

1. \( 75 \times 8 = 600 \)
2. \( 7 + 2 = 9 \)
3. \( 50 \times 9 = 450 \)
4. \( 600 + 450 = 1050 \)
5. \( 1050 - 3 = 1047 \)

Finally:
\[
812 = 1047 - 235
\]

This solution is incorrect, so let's try a different approach:

We can try another combination:

1. \( 75 \times 8 = 600 \)
2. \( 50 \times 7 = 350 \)
3. \( 350 + 3 \) - \( 2 \times 35 = 82 \)

\[
(75 \times 8) + (50 \times (7 + 2)) + 3 = 812
\]

This approach also fails. Let's calculate again by the following method:

1. \( 75 \times 8 = 600 \)
2. \( 50 \times 7 = 350 \)
3. \( 350 + 3 =  353 \)
4. \( 600 - 353  = 47 \)
5. \( 50 \times 2 = 812\)
