Instructions

1
Skip the 1, because it is not written in notation. It is just written as "1."

2
Subtract 5 from 7 to get the result of the 2nd notation (7-5). The result is 2.

3
Look at the 90 degree symbol in the third position. This one does not translate directly to 3, but it does show the angle of the watch's hands and the fact that it is between 2 and 4 should be indicator enough.

4
Add 2 plus 2 to find the result of the fourth equation (2+2).

5
Skip 5, because it is also written in standard form.

6
Divide 36 by 6 for the next equation. Because 6 x 6 = 36, the answer is 6, and this is the number in the bottom position.

7
Calculate 4 + 3 for the next equation.

8
Multiply 2 x 2 x 2 for the next equation, which is 2 cubed. The result is 8.

9
Remember how Roman numerals work for the next number -- IX is the same as 10 minus 1 because the 1 symbol is in front of the 10 symbol. Your result is 9.

10
Skip the next one because it is just a question mark; you'll have to remember it based on its placement.

11
Remember that the square root of 121 is 11. There is no formula you can do in your head for this, so you'll just have to remember.

12
Look at the last notation as an angle -- 0 degrees. Again, remember what it is by its placement.



Someone will put the photo of this watch?? let's see who is the first
