phrasal verb

to make a total amount or number of sth 总共是;总计为The numbers add up to exactly 100.这些数字的总和恰好是100。Their earnings were £250, £300 and £420, adding up to a total of £970.他们的收入分别是250英镑、300英镑和420英镑,共计970英镑。

Add up to and number can be used to emphasize the process of calculating a total through mathematics or counting; total and amount to sth focus more on the number/amount rather than the process of arriving at the result. Total and amount to sth are used especially in business writing when describing the performance of a company or industry. Number usually has people as the subject of the sentence; total is the only other verb that can be used like this. * add up to和number强调通过计算得出总数的过程; total和amount to sth更着重于得出的数目或数量,而非计算的过程。total和amount to sth尤用于描述公司或产业业绩的商业写作中。number的主语通常是人,本组同义词中只有total也可这么用The crew totalled / numbered sixteen.机组人员共计十六人。The crew added up to/amounted to sixteen. ˈrun to sth
