Expression Analysis

Let's break down the given expression step by step:

1. 16x12: This is a multiplication operation between 16 and 12. 2. 34x17: This is a multiplication operation between 34 and 17. 3. 28x20: This is a multiplication operation between 28 and 20. 4. 909:9: This is a division operation between 909 and 9. 5. (520-502): This is a subtraction operation between 520 and 502. 6. (520-502)x13: This is a multiplication operation between the result of step 5 and 13. 7. (520-502)x13:6: This is a division operation between the result of step 6 and 6. 8. 755:5: This is a division operation between 755 and 5. 9. 18x18: This is a multiplication operation between 18 and 18. 10. (89-73): This is a subtraction operation between 89 and 73. 11. (22-44-11x20-10x10): This is a combination of subtraction and multiplication operations. 12. (22-44-11x20-10x10):8: This is a division operation between the result of step 11 and 8.

Now, let's calculate the expression step by step.

Calculation Steps

1. 16x12 = 192 [[1]] 2. 34x17 = 578 [[2]] 3. 28x20 = 560 [[3]] 4. 909:9 = 101 [[4]] 5. (520-502) = 18 [[5]] 6. (520-502)x13 = 234 [[5]] 7. (520-502)x13:6 = 39 [[5]] 8. 755:5 = 151 [[6]] 9. 18x18 = 324 [[7]] 10. (89-73) = 16 [[8]] 11. (22-44-11x20-10x10) = -312 [[9]] 12. (22-44-11x20-10x10):8 = -39 [[9]]

Now, let's substitute the calculated values back into the original expression and simplify it further.

Simplification

16x12 + 34x17 - 28x20 + 909:9 - (520-502)x13:6 + 755:5 + 18x18 - (89-73)x19 + (22-44-11x20-10x10):8

= 192 + 578 - 560 + 101 - 234 + 151 + 324 - 16 + (-39)

= 657

Therefore, the value of the given expression is 657.
