To solve the expression \( 5 + 5 \times 5 \), you need to follow the order of operations (often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).
First, do the multiplication: \( 5 \times 5 = 25 \).
Then, do the addition: \( 5 + 25 = 30 \).
So, \( 5 + 5 \times 5 = 30 \).
