Many questions are purely computational and can easily be solved with a calculator.
The downvote tooltip says:
This question does not show any research effort; it is not clear or useful
Questions that can easily be solved with a calculator are like questions that can easily be Googled. They "do not show any research effort."
Is it acceptable to downvote those questions?
What is 1 + 1 = ?
I think the example question above should be downvoted.
What is 235.382 * (−4.69) + √(6)−3 ÷ 168370
The second example question is in a gray area. Does it warrant a downvote?
