By BY

Today's mentalfloss.com Brain Game Think Thursday challenge is a bit more involved than most, but it's still easy to play. Just please make sure to read these instructions carefully before tackling it:

Your goal: Make the equation [  1  2  3  4  ] work by adding some combination of the four basic mathematical symbols +  -  ×   / and the equals sign = Important: You cannot change the position of the digits, nor add any digits, symbols, or marks other than some combination of the five mentioned.

TWO CORRECT EXAMPLES: 1 2 = 3 × 4 - 1 + 2 + 3 = 4 With a few minutes' work, in addition to the examples above, we came up with seven different ways to do it. Can you find those seven (and/or others)?

Here are 7 selected SOLUTIONS.

SEVEN SELECTED SOLUTIONS:

1 2 / 3 = 4
1 - 2 = 3 - 4
1 - 2 - 3 = - 4
1 = 2 + 3 - 4
1 2 = - 3 × - 4
- 1 2 = - 3 × 4
- 1 + 2 = - 3 + 4

Did you come up with any different solutions? Feel free to share them with us in the comments below. Thanks for playing!
