Ok, in keeping with the maths questions of late, here's one that combines numbers AND letters...
Some letter blocks have been put together to spell out the following sum:
ONE + TWELVE = THIRTEEN
Using all these blocks, rearrange some of them to get a different sum, which is also correct.
Then replace the I with the E and insert another "+" block. By rearranging the blocks again, once more another correct result can be achieved.
Can you find the two new versions of the equations?
