Solution:
According to the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), you should perform multiplication before addition.So, for the expression $$3 + 4 \times 8$$, you would first multiply 4 by 8.$$4 \times 8 = 32$$After that, you add 3 to the result.$$3 + 32 = 35$$Therefore, $$3 + 4 \times 8 = 35$$.
