where do I place the parenthesis in this problem so that the answer is 7?
4-3*2+6=7
To place the parentheses in the problem to get the answer as 7, you need to prioritize the order of operations. The order of operations is as follows:
1. Parentheses
2. Exponents (i.e., powers and square roots, etc.)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
Let's apply this to the given problem: 4-3*2+6.
To get the desired answer of 7, you need to enclose the part of the expression that you want to be calculated first in parentheses. In this case, you want to ensure that the multiplication 3*2 is performed before any other operations.
So, you can place the parentheses around 3*2 like this: 4-(3*2)+6.
Now, let's evaluate it step by step:
1. Solve the expression inside the parentheses: 3*2 = 6.
2. Now, the problem becomes: 4-6+6.
3. Perform the subtraction: 4-6 = -2.
4. Finally, perform the addition: -2+6 = 4.
Thus, by placing the parentheses as mentioned, the answer is not 7, but rather 4.
