请教大家，如果上完APOS Introduction to algebra A, 之后应该学introduction

To algebra B 还是 introduction to counting & possibility?

• 先上intro to number theory吧？难度系数比较小，counting and probability难度 -两女宝妈- ♀ (72 bytes) () 09/04/2023 postreply 17:01:09

• 都可以。intro to counting and probability需要的预备知识更少。 -HappyWed- ♀ (0 bytes) () 09/04/2023 postreply 17:14:02

• 或者是否在introduction to algebra A 之后学Mathcourts如何？不好意思，问得问题很初级 -bayuquan- ♀ (0 bytes) () 09/04/2023 postreply 17:32:36

• Mathcounts 是一个初中数学竞赛，它不是某门专项的数学知识课程。可以在数学课之外练习一下 -HappyWed- ♀ (0 bytes) () 09/04/2023 postreply 18:03:05
