To evaluate the expression 1[8 - 4(4 - 5)], you follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, solve the expression inside the inner parentheses: 4 - 5 = -1.

Then, evaluate the expression inside the square brackets: 8 - 4 * (-1).

Perform the multiplication: 4 * (-1) = -4.

Now, subtract: 8 - (-4) = 8 + 4 = 12.

Finally, multiply by 1: 1 * 12 = 12.

So, the result of the expression 1[8 - 4(4 - 5)] is 12.
