Default SVM classifier One-vs-One and One-Vs-All clarification

I don't understand the question correctly here. For one-vs-one should we pick 2 digits (e.g. 1 and 2) and make them +1 and -1 and rest of the data ignore and try the classification and repeat the exercise for 1,2 1,3 1,4 etc. That would be 10C2 combination. Also for one-vs-all should we do the same but instead of ignoring all the data should we make them all -1?

Then how do we classify 4-vs-all etc.? Really appreciate some help here.
