Hypnosis is the fastest and most effective way to get into the subconscious mind. Each suggestion was nine times stronger than the usual situation. This experimental research aims to provide a description of the effect of learning accompanied by self-hypnosis on increasing mathematics scores. The test is done by comparing the post-test scores of the control group and the experimental group through the t test for the independent sample. This experimental study concluded that the method of learning mathematics with self-hypnosis was able to improve students' mathematical abilities. This conclusion is evidenced by the significant difference between the mean of group 1 as the control variable and group 2 as the experimental variable after being given treatment or stimulus for a period of 1 semester
