…tallying systems, was not commonplace in the seventeenth century. Not to mention old measurement standards, balanced ternary was written about in the sixteenth century (see the cossist Stifel's 1544 Arithmetica Integra) and possibly the ancient Indian Vedas.
Negative numbers were popularized in Europe by Michael Stifel's 1544 book Arithmetica Integra, where he called them "numeri absurdi." The concept emerged gradually, as mathematicians found they were useful for solving equations as a kind of "notional convenience," even though they did not think…
……记账/计分系统，在十七世纪并不普遍。更不用说古老的度量标准了，早在十六世纪就有人写过平衡三进制（balanced ternary）（参见代数学家施蒂费尔 1544 年的《Arithmetica Integra》），而且古代印度吠陀经里可能也有记载。

负数在欧洲普及开来，归功于米夏埃尔·施蒂费尔（Michael Stifel）1544 年出版的《Arithmetica Integra》一书，他在书中称其为“荒谬数”（numeri absurdi）。这个概念是逐渐浮现出来的，因为数学家们发现它们作为一种“概念上的便利”在解方程时很有用，尽管他们当时并不认为……
