Perform the indicated operation.
10-15 ÷ (3)(6) -12
You need to provide parentheses to that, or else the order of operations in unclear. You just don't go from left to right. As far as the mathematical operations are concerned, you should be able to do those yourself.
sorry..that is the way it was presented to me
To perform the indicated operation, we need to follow the order of operations, which is known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Let's break down the problem step by step:
1. Start with the division part: 15 ÷ (3)(6)
Since there are no parentheses or exponents, we can move on to the multiplication.
15 ÷ (3)(6) becomes 15 ÷ 18
Now, perform the division: 15 ÷ 18 = 0.8333 (rounded to four decimal places)
2. Next, we substitute the result back into the equation:
10 - 0.8333 - 12
3. Finally, perform the subtraction from left to right:
10 - 0.8333 = 9.1667
9.1667 - 12 = -2.8333 (rounded to four decimal places)
Therefore, the final result of the operation 10 - 15 ÷ (3)(6) -12 is approximately -2.8333.
