To solve the expression 68:(7-41)-18•4, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. Start with the parentheses: (7-41). Subtracting 41 from 7 gives us -34.

2. Next, perform the multiplication: -18•4. Multiplying -18 by 4 gives us -72.

3. Now, we can substitute the results back into the expression: 68:-34-72.

4. Finally, perform the division and subtraction from left to right: 68 divided by -34 is -2, and then subtracting -72 gives us -2 - (-72) = -2 + 72 = 70.

Therefore, the solution to the expression 68:(7-41)-18•4 is 70.
