Synaesthesia mathematics makes mathematics more stereoscopic and mobilizes all the senses. By unifying the information input by all the senses, we can develop our interest in learning to a deeper level, smoothly transition to the abstract logical thinking mode and master the basic knowledge of mathematics.

Extension: Synaesthesia, also known as "empathy", is a rhetorical format that uses image language to transfer feelings, communicate and interweave people's different feelings such as vision, smell, taste, touch and hearing, and transfer words that originally express a sense to express b sense, making the image more vivid and novel. Synaesthesia is to communicate the feelings of different senses, cause the transfer of feelings through association, and communicate with various sensory organs in literary creation and appreciation. It means that vision, touch, smell, hearing and other functions can communicate, regardless of boundaries. It is a physiological and psychological phenomenon that people have, and it is also inseparable from the cultivation of people's social practice. In synaesthesia, color seems to have temperature, taste seems to have image, and warmth seems to have weight. Such as "warm red" and "cold blue", it seems that vision and touch are interlinked, such as "bright" and "loud", as if vision and hearing are interlinked, such as "lively" and "calm", as if touch and hearing are interlinked. In modern psychology or linguistics, these are all "synaesthesia". history
