I've been messing around with numbers and since I couldn't find anything like this on google I thought I'd post it here.
If you haven't heard of ambigrams, here is the definition
Quote: "A design that may be read as the same word or phrase (or sometimes two different words or phrases) when oriented in two different ways, usually when reflected in a vertical axis or when rotated through 180 degrees"
and an example:
I wondered if there were mathematical ambigrams, but as I said I couldn't find any so I tried to make my own. These work best with seven segment digits, like those used on digital clocks. Here is the first one:
9 - 6 + 2 = 5
when viewed upside down it reads
5 = 2 + 9 - 6
which is also correct. This is the same sum though and I thought a more interesting ambigram would be one that produced two different equations.
52 x 2 = 82 + 22
Which is equal to 104. When viewed upside down this reads
22 + 28 = 2 x 25
Which is equal to 50!
I thought these were quite interesting and worth sharing.
Snobbery is a privilege of the ignorant.
