Add parentheses so that the equation is correct.... 7+9x3-1=25 Will someone please help me out here. Thanks!!
Got it!!!...it's 7+[9x(3-1)]=25
Thanks for the quick response!
why not try a few possibilities, there are not that many
(7+9)x3-1
(7+9)x(3-1)
7+9x(3-1)
Do any of these work?
Hmmm whats the answer I have no clue?

To make the equation 7 + 9 * 3 - 1 = 25 correct by adding parentheses, we need to determine which operations to prioritize. One common rule is to prioritize multiplication and division over addition and subtraction. With this in mind, we can place the parentheses as follows:
7 + (9 * 3) - 1 = 25
In this new arrangement, we compute the multiplication operation inside the parentheses first. 9 multiplied by 3 equals 27. Replacing the parentheses with the calculated value, the equation becomes:
7 + 27 - 1 = 25
Now we can proceed with the addition and subtraction operations from left to right:
7 + 27 = 34
34 - 1 = 33
Therefore, the equation 7 + (9 * 3) - 1 = 25 is not correct.
