Hi, JJ163 answer is maybe D. I have discussed this problem in another post, called "HELP JJ163" with some other people.
Maybe you can change the answer

using the property of inequalities or writing a number line will help solve this problem.

Thank you

135 有道ds数学，是20个黄的，20个红的，20个绿的token，然后有个小姑娘从中拿出12个，等距离地放在一个板子的还是什么东西的上沿上【我承认这段叙述没看明白】。然后问“她这种放发是多少种放法的的其中之一”。【非常诡异的问题】
条件一。把红的token换成绿的token、绿的token换成红的token之后，可能的放法的数量不变
条件二。红的和绿的token一共12个。
楼主好像选的c

这题我肿么觉得应该是E啊？怎么算都得不出？

127题OR可以包括红的and三角的，应该是C吧

163~

163 V1 有一个题目做了很久后来发现还是画数轴来得快。问一个数是不是距离0.001比距离0.1要近？条件一，距离0.0001比距离0.1要近条件二，距离0.001比距离0.01要近题目没记错的话我当时选E

的答案是D吧……求确认
