4. But be it in the mathematics as it will, whether it be clearer, that, taking an inch from a black line of two inches, and an inch from a red line of two inches, the remaining parts of the two lines will be equal, or that IF YOU TAKE EQUALS FROM EQUALS, THE REMAINDER WILL BE EQUALS: which, I say, of these two is the clearer and first known, I leave to any one to determine, it not being material to my present occasion.
4. Baina, dena dela matematikan gertatzen dena, bakoitzak ebazteko uzten dut ea zer den argiago eta lehenbizi ezagutzen duguna, bi hatzeko lerro beltz bati hazbete eta bi hatzeko lerro gorri bati hazbete kenduz gero, lerro batean eta bestean geratzen diren zatiak berdinak direla, ala berdinei berdinak kenduz gero, hondar berdinak geratzen direla, ez baitu horrek, ukan ere, garrantzirik nire oraingo xederako.
