The numbers and symbols below are placed onto six vertical strips of paper:

        8    -    2    9    ×    1
        +    1    =    5    1    5
        =    9    0    2    ÷    6
        1    =    5    6    =    1

Rotate and rearrange the strips so that four valid equations appear across the rows.

Note: Consider the numbers as they appear on a digital watch; 0, 1, 2, 5 and 8 are the same when rotated 180°, while 6 and 9 rotate to each other.
