Final answer:
To make the expression 26-6-5×4 equal to 10, parentheses can be placed as follows: (26-6)-(5×4). This respects the order of operations and gives the correct result of 10.
Step-by-step explanation:
The student asked to place parentheses in the expression 26-6-5×4 to make it equal to 10. To correctly place the parentheses, we need to understand the order of operations, often remembered by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). By placing parentheses in the expression, we change the order in which the operations are carried out.
Note that we want to make the expression equal to 10, so one possible way to insert the parentheses is as follows: (26-6)-(5×4). Evaluating the multiplication first, 5×4 equals 20. Then we subtract 6 from 26 to get 20. Lastly, we subtract the two results to get 10: (26-6)-(5×4) = 20-20 = 10. This way, we have correctly placed the parentheses to achieve the desired outcome.
