Answer 2

To solve this expression, you should 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):

Given expression: 7 * 7 + 31 / 10 * 8 - 40 / 6 * 9 / 4 * 9

1. First, perform the multiplications and divisions from left to right:

   • 7 * 7 = 49
   • 31 / 10 = 3.1
   • 3.1 * 8 = 24.8
   • 40 / 6 = 6.666...
   • 6.666... * 9 = 60
   • 60 / 4 = 15
   • 15 * 9 = 135

2. Now, substitute these values back into the expression: 49 + 24.8 - 135

3. Finally, perform the additions and subtractions from left to right: 49 + 24.8 = 73.8 73.8 - 135 = -61.2

So, the result of the expression 77+31/108-40/69/49 is approximately -61.2.
