Simplify:
$$48+[25-\{20-(11-16÷2\times 4)\}]=?$$

Using the BODMAS rule, follow the order: Brackets, Of, Division, Multiplication, Addition, Subtraction.
Given expression:

$$48+[25-\{20-(11-16÷2\times 4)\}]$$

Step 1: Solve inside the innermost small parentheses $(11-16÷2\times 4)$

* Division first: $16÷2=8$
* Expression becomes: $(11-8\times 4)$
* Multiplication next: $8\times 4=32$
* Expression becomes: $(11-32)=-21$

Step 2: Substitute back into curly brackets $\{20-(-21)\}$

$$\{20+21\}=41$$

Step 3: Substitute back into square brackets $[25-41]$

$$[25-41]=-16$$

Step 4: Final addition

$$48+[-16]=48-16=32$$
