36:9-8:1:4+98-71

To solve the expression \( 36:9 - 8:1 + 4 + 98 - 71 \), we follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. First, we handle the divisions:
   • \( 36:9 = 36 \div 9 = 4 \)
   • \( 8:1 = 8 \div 1 = 8 \)

So we can rewrite the expression as: \[ 4 - 8 + 4 + 98 - 71 \]

2. Now we compute the expression from left to right:
   • \( 4 - 8 = -4 \)
   • \( -4 + 4 = 0 \)
   • \( 0 + 98 = 98 \)
   • \( 98 - 71 = 27 \)

Thus, the final answer is \( 27 \).
