Telcraft (scorelore or reckonlore) (English: Mathematics) is the lore of scorings, or the hilering of heedings such as score, room, shift, and forebuilding. Benjamin Peirce called it "the worldken that draws needed outwen". Through foredeeming and wordlock mulling, scorelore arose from notching, reckoning, deeming, and the learning of sheathes and shapes. There was a stepmeal unfolding until the H16th, when the first searful reckoners were built.
