To find the solution to the expression 10 ÷ 2 − 3 × 1, one must follow 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). In this case, the first step involves performing the division operation. Dividing 10 by 2 yields a result of 5.
Next, the expression now reads 5 − 3 × 1. According to the order of operations, multiplication is performed before subtraction. Therefore, we calculate 3 multiplied by 1, which equals 3. This transforms the expression into 5 − 3, allowing us to proceed to the final step.
Finally, we subtract 3 from 5, resulting in a value of 2. For students seeking assistance with such mathematical problems, a gcse maths tutor online can provide valuable guidance and support, ensuring a thorough understanding of the concepts involved in solving similar expressions.
