Vlad I think people would complain a lot less if it showed a nice Javascript calculator like:
instead just a result like:
The big button on the basic Google calculator takes you to an advanced calculator:
but a neater way to implement this would be to just have one calculator and integrate the basic layout as a tab, and add a conversion tab (for most-frequent currency, weight and volume conversions).
So you'd have Basic | Conversion | Algebra | Trigonometry | Calculus tabs.
Add two big buttons under the calculator that says something akin to search instead | ask assistant instead.
Now you can divert all detected math and currency searches to this widget first.
You could use the rest of the vertical page for (current session) calculator history, which would make the page feel even less empty and unused.
Oh and the calculator should be captive for numbers, enter, shift-enter, parentheses, etc.
(If you'd want (yay scope creep), later on in development you could add an overflow ▼ / ⋮ containing CompSci, Accounting, Engineering and other specialized layouts. But that would be much lower priority.)
