The expression $100 \div 4 (2+3)$ can be solved using the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. First, simplify inside the parentheses: $2 + 3 = 5$

2. Now the expression becomes: $100 \div 4 \times 5$

3. Division and multiplication have the same priority, so we solve from left to right: $100 \div 4 = 25$

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

Thus, the result is: $\boxed{125}$
