A calculator having a handwriting board, comprising a calculator main body (100) and a handwriting board main body (200). The edges of the calculator main body (100) and the handwriting board main body (200) are at least provided with a rotating mechanism (300); the handwriting board main body (200) is rotatably connected to the calculator main body (100) by means of the rotating mechanism (300); the rotating mechanism (300) comprises a connecting member (310); the two ends of the connecting member (310) are respectively provided with a first rotating shaft (320) and a second rotating shaft (330) in a penetration mode; a first mounting groove (110) and a second mounting groove (210) are respectively formed in the edges of the calculator main body (100) and the handwriting board main body (200); moreover, a pair of first rotating holes (120) are symmetrically formed in two sides of the first mounting groove (110), and a pair of second rotating holes (220) are symmetrically formed in two opposite sides of the second mounting groove (210); and the two ends of the first rotating shaft (320) are respectively and rotatably connected to the two first rotating holes (120), and the two ends of the second rotating shaft (330) are respectively and rotatably connected to the two second rotating holes (220). When the handwriting board main body (200) is flipped, the connecting member (310) can be flipped along with the handwriting board main body (200), so that the handwriting board main body (200) cannot abut against the connecting member (310) when being flipped by 180 degrees, and thus, flipping is smooth and stability is good.
