The expression is:

$100 \div 4(2+3)$

Following the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)), we start by solving inside the parentheses:

$2 + 3 = 5$

Now the expression becomes:

$100 \div 4(5)$

Since multiplication and division are performed from left to right, we first do the division:

$100 \div 4 = 25$

Now multiply by 5:

$25 \times 5 = 125$

Thus, the final answer is:

$\boxed{125}$
