N. B. In the first Example, I take 4 from 7, and there remains 3, and so place it down, and proceed to the End of that Example.
But in the second Example, I cannot take 8 from
and it makes 17, then 8 from 17, and there refts 9, which I place down, and carry one that I borrowed to the 7, and it makes 8; then 8 from 2 I cannot, but I borrow 10, and add it to the 2, and it makes 12 ; then 8 from 12, and there remains 4, which place down ; and fo proceed to the End, remembring to carry one to the next Figure when you borrow the 1o.
If you add the Remains to your least given Number, the Sum will be the greater Number given, which is the Proof.
