Answer 2

To solve this expression, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right):

1. First, perform calculations inside parentheses: $35 - 15 = 20$

2. Perform multiplications and divisions: $67 * 90 = 6030$ $6 : 250 = 0.024$ $4.5 * 20 = 90$ $20 * 100 = 2000$ $8.3 * 20 = 166$ $14:7 = 2$

3. Subtract the result of the parentheses calculation from step 1: $20 * 4.5 = 90$

4. Perform additions and subtractions: $3 - 5 = -2$ $6030 - 0.024 - 90 + 2000 - 30100 - 166 + 2 = -22128.024$

5. Finally, add 10100: $-22128.024 + 10100 = -12028.024$

So, the final result of the expression is approximately $-12028.024$.
