You could call a funda if you so desire. While it is recommended that you read some more of the funda entries here (and perhaps explore further when you find the links to the others) before actually assuming you know a funda, the fundamental funda welcomes your voice, questions, queries, posers, and even meandering stories even if you are a total stranger. Keep in mind that foolish assumptions or negativity might not be as welcome, but the beauty of a phone is you can hang it up if you don't like what you hear when you call someone. So can the funda.

If the above link is confusing, you might find this simpler (though math rules are applied randomly, so maybe not):

6 + 4 x 3 / 10
5 - 3
27 - 7 / 4
365982 / 365982
64 / 16
(6 x 9) + (2 x 5) / 8
42 / 21
