Let's solve the expression $100 \div 4(2 + 3)$ step by step:

1. Start by simplifying the parentheses: $2 + 3 = 5$ Now, the expression becomes: $100 \div 4(5)$

2. According to the order of operations (PEMDAS/BODMAS), we first handle the division: $100 \div 4 = 25$ So the expression is now: $25(5)$

3. Finally, multiply 25 by 5: $25 \times 5 = 125$

The result of the expression is $125$.
