Final answer:

To solve the expression 8+3⋅42, follow the order of operations: multiply 3 by 42 to get 126, and then add 8 to get 134.

Step-by-step explanation:

The expression given is 8+3⋅42. To evaluate it, we must adhere to the order of operations, often remembered by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Since there are no parentheses or exponents to deal with, we move onto multiplication before addition. We have to multiply 3 by 42 first and then add 8 to the product.

Multiplication Step: 3 × 42 = 126

Addition Step: 8 + 126 = 134

Therefore, the evaluated result of the expression 8+3⋅42 is 134.
