Easy to operate, can directly input the answer, enter (check), press enter (the next), enter the answer again,
Practice in the options menu can be set up special (such as special multiply or divide),
Operand can choose (0 ~ 9) within 10 or 20 (0 ~ 19), within the scope of the division for the quotient and the divisor
