The given expression is:

\[
100 \div 4 (2+3)
\]

### Step 1: Simplify the parentheses
First, solve the expression inside the parentheses:
\[
2 + 3 = 5
\]

### Step 2: Multiply and divide (following the order of operations)
Now, the expression becomes:
\[
100 \div 4 \times 5
\]

### Step 3: Apply the order of operations (PEMDAS/BODMAS)
According to the order of operations, you must divide and multiply from left to right:
\[
100 \div 4 = 25
\]
\[
25 \times 5 = 125
\]

### Final Answer:
\[
100 \div 4 (2+3) = 125
\]
