To solve this arithmetic expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression given is: 99 - (-41) - 72 + 31

Step 1: Solve the expression within the parentheses first: 99 - (-41) = 99 + 41 = 140

Step 2: Now, the expression becomes: 140 - 72 + 31

Step 3: Perform subtraction from left to right: 140 - 72 = 68

Step 4: Perform addition from left to right: 68 + 31 = 99

So, the answer is 99.
