30 ÷ 1 - 30 × 1 can be solved using the order of operations, which is commonly represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
First, we perform multiplication and division from left to right:
30 ÷ 1 = 30
30 × 1 = 30
Next, we perform subtraction:
30 - 30 = 0
Therefore, the value of the expression is 0.
