Faster Computers

For a computer carry out the operation 117+10 it uses the following form: 1010111+0101=1111111
And for him this digits increase seems no problem, therefore to his capacity of "management" of data looks barely interminable. And in the current uses there are barely no differences in their performance.
However for more complex operations, that involve very big numbers or imply a big quantity of detailed results, this little complication is feel in the speed and efficiency of the computers.
For become them more quick and efficient, in these circumstances, will be enough to change them calculation base, from binary system to a decimal system.
Instead of the current passes-not passes, it becomes a passes one, two, three, four, five, six, seven, eight and nine times, or does not pass.
To do 117+10 the computers would use now to following form:
711+01=721
That would reflect for the user the value 127.
Without changing his current form of "think" we would put the computers "thinking" as us but as a mirror.
