    this is a weird question. 4+8=12 the closest number to 12 here is 10

    Calculate the exact result and the absolute distance to the estimates. The one with the smallest distance is the best estimate.

    Weirdness depends on the point of view. Also most well-defined things are trivial.

    I would think that 4 rounded is 10 and 8 rounded is 10 so 20 would be correct

    i guess we can view it as a sort of practice before learning epsilon delta proofs

    why would you take estimates before adding?
