Explanation
ลบ is easiest to understand as removing something. In daily life it is very common with phones and computers, as in ลบรูป “delete a photo,” ลบข้อความ “delete a message,” and ลบไฟล์ “delete a file.” In math, it is the opposite of บวก “add,” and the basic pattern is A ลบ B เท่ากับ C. As an adjective, it appears in phrases such as เลขลบ “negative number,” เชิงลบ “negative/unfavorable,” and ผลตรวจเป็นลบ “the test result is negative.”
Usage
