Answer 2

To solve the expression $407 \times (36900 - 255 \times 144) - 318 \times 92$, 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. Calculate inside the parentheses: $36900 - 255 \times 144 = 36900 - 36720 = 180$

2. Substitute the result back into the expression: $407 \times 180 - 318 \times 92$

3. Perform the multiplications: $407 \times 180 = 73140$ $318 \times 92 = 29256$

4. Perform the subtraction: $73140 - 29256 = 43884$

So, $407 \times (36900 - 255 \times 144) - 318 \times 92 = 43884$.
