Interesting project.
I guess this is the first search engine to employ serious language interpretation.
Here's a few things I tried ...
add 25 and 30 ---> 55. Good!
square root of 9 plus 16 ---> 3+16 ---> 19. Good!
time 20 minutes after 2:50pm ---> 3:10pm Good!
average of 45, 60 and 70 ---> 1/2(45+(60^70)) What the ...!
reduce 20 by 5 ---> solve 20x5=0 ---> No solutions exist. What the ...!
distance from Earth to Moon ---> 395501km Good!
Bathurst ---> Banjul, Gambia Pop 34589. No Bathurst, Australia.
I was impressed with many other calculations I tried, using a combination of natural language and number.
However "2 to the power of 3 plus 3 to the power of 2" was interpreted as 2^(3+3^2) instead of 2^3+3^2.
Works great when it's right but you need to be savvy when things go amiss?
