Why id it "to examining" not "to examine"?
"Before we continue on to examining Strassen’s algorithm, let us review where the components of equation (4.16) came from."
In this case "to" is a preposition and not an infinitive marker. The pattern is "continue on to X", where X, a noun or noun phrase, is the destination. In this case the "destination" is "examining Strassen's algorithm".
