To solve the equation:

$10 \times 15 + 8$

Follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)):

1. First, multiply $10 \times 15 = 150$
2. Then, add $150 + 8 = 158$

So, the solution is:

$\boxed{158}$
