I use Google for calculations when I am sitting on my PC. Google Calculator seems to work fine for small calculations but have you tried a bigger calculation that gives a smaller result? It seems that Google Calculator does not know mathematics and fails in this condition. Surprised ?
Just type the following equation in Google search and see what result you get
Everyone knows that the result is 1 but see what Google Calculator is showing :
Why is this happening : Actually Google Calculator fails at big calculations that is why giving incorrect result. The equation when compared to the result is very very big that is why the algorithm fails to give the accurate answer.
