add parentheses to 9+8*7-6*5+4*3+2=105
(9+8)*(7-6)*5+4*(3+2)
If you add 9+8 you get 17, 7-6 is 1, and 3+2 is 5. 17*1 is 17, 17*5 is 85, 4*5 is 20, 85+20 is 105. That is the answer to this math question.
To add parentheses to 9+8*7-6*5+4*3+2=105, you need to follow the order of operations or the PEMDAS rule. Here's how to do it step by step:
Step 1: Start by multiplying any numbers or expressions within parentheses. In this case, there are no parentheses to start with.
Step 2: Next, perform any multiplication or division from left to right. Multiply 8*7, 6*5, and 4*3.
9 + 56 - 30 + 12 + 2 = 105
Step 3: Restate the expression using the results of the multiplication or division. This gives us:
9 + 56 - 30 + 12 + 2 = 105
Step 4: Now, perform any addition or subtraction from left to right.
65 - 30 + 12 + 2 = 105
Step 5: Continue performing any remaining addition or subtraction.
35 + 12 + 2 = 105
47 + 2 = 105
49 = 105
Since 49 is not equal to 105, we can see that the original equation does not equal 105.
If you want to add parentheses to this equation, you need to clarify where the parentheses should be placed.
