“0.1 + 10% = 0.11 是错的？”小米客服回应引争议 | Is “0.1 + 10% = 0.11” Wrong? Xiaomi Customer Service Response Sparks Debate

近日，一段抖音视频引发网友热议：一位女子在辅导孩子数学作业时，使用小米手机计算“0.1 + 10% = 0.11”，吐槽计算错误，并联系了小米客服。
Recently, a TikTok (Douyin) video went viral: while helping her child with math homework, a woman used a Xiaomi phone to calculate “0.1 + 10% = 0.11”, complained it was wrong, and contacted Xiaomi customer service.

客服回应建议她“清理手机缓存”来解决问题。
The customer service representative suggested she “clear the phone's cache” to fix the issue.

这一回应更是引发网友质疑：难道客服也认为 0.1 + 10% = 0.11 是错的？
This response sparked even more debate online: does the customer service also believe that 0.1 + 10% = 0.11 is incorrect?

这张图展示了两个手机计算器对“0.1 + 10%”的不同结果：左边是 0.11，右边却是 0.2，引发大量网友热议。
This image shows two smartphone calculators producing different results for “0.1 + 10%”: one shows 0.11, the other 0.2, sparking widespread discussion.

看似简单的数学题，却暴露出两个计算器在处理百分比时的逻辑差异。
Though it seems like a basic math problem, it reveals how differently each calculator interprets percentages.

左边的计算器将“10%”视为“0.1 的 10%”，即 0.1 × 10% = 0.01，再加上原数 0.1，得出正确结果 0.11；
The left calculator treats 10% as 10% * 0.1 = 0.01, then adds it to 0.1, resulting in the correct answer: 0.11.

而右边则直接把 10% 当作 0.1 加进去，因此显示 0.2。
The right one directly adds 0.1 (interpreting 10% as a fixed 0.1), giving 0.2.

正确理解是：
The correct interpretation is:

10% 是指某个数的十分之一，因此 0.1 + 10% 应被理解为：
10% means “10 percent of something,” so “0.1 + 10%” should be understood as:

0.1 + (10% × 0.1) = 0.1 + 0.01 = 0.11

技术的发展本应提升我们的效率，而不是削弱我们的能力。
Technology should enhance our efficiency, not diminish our thinking abilities.

计算器确实能解决复杂计算，但若连最简单的加法都无法独立思考，就显得过度依赖。
Calculators are useful for complex problems, but if we can't solve even basic ones mentally, that signals over-reliance.

尤其在教育阶段，如果学生对“10%”的含义都不能正确理解，而是依赖机器的“黑箱”操作，那将严重影响其数学思维能力的发展。
Especially in education, if students fail to understand what “10%” truly means and instead depend on black-box calculations, their mathematical thinking will suffer.
