- Higher rates would attract foreign investors looking to buy Brazilian government bonds priced in reals.
而高利率会吸引外国投资者购入以雷亚尔计价的巴西国债。 - Mathematicians are familiar with this; common problems in algebra are more tractable when considered over the complex numbers than over the reals, even though complex arithmetic is more difficult.
数学家对此很熟悉;如果将代数中的常见问题考虑成复数而不是实数时,那么这些问题就更容易处理,尽管复数算法较难。 - After all, mathematicians and engineers have used integers and reals successfully for a long time, without knowing they were manipulating class instances.
毕竟,数学家和工程师长期成功地使用着整数和实数,并不知道他们正操作着类的实例。
