So, many unreliable quick ways emerge to solve the math problems. Some of the ways sometimes led to misconceptions in mathematics, which would obstruct the ability of the students’ HOTS. This article aims to show some of the misconceptions that are often encountered in solving mathematics problems. By recognizing the misconceptions, teachers are expected to avoid them and optimally anticipate the achievement of the “true” objectives of learning mathematics.
