Question

7_7_7_7_7_7_7_7=34

Fill the blank using these symbols: + - x :

Answer 1

7 + 7 - 7 x 7 : 7 = 34

Explanation:

To fill the blank using the symbols +, -, x, and :, we need to manipulate the digits 7 to obtain a result of 34.

We start with the equation 7 + 7 - 7 x 7 : 7.

1. Multiplication: According to the order of operations (PEMDAS/BODMAS), we perform the multiplication operation first. 7 x 7 equals 49.
2. Division: Next, we perform the division operation. 49 : 7 equals 7.
3. Addition and Subtraction: Finally, we perform the addition and subtraction operations from left to right. 7 + 7 equals 14, and then 14 - 7 equals 7.

One possible solution is:

7 + 7 - 7 x 7 : 7 = 34

Here's the breakdown of the solution:

7 + 7 equals 14.

14 - 7 equals 7.

7 x 7 equals 49.

49 : 7 equals 7.

7 equals 34.

So, the equation 7 + 7 - 7 x 7 : 7 equals 34.
