The TI-7 MathMate is a basic educational calculator by Texas Instruments designed for students in grades K-3. The MathMate was unique in the fact that it automatically performed order of operations. The MathMate slotted in between the TI-108 and the TI-12 Math Explorer.
The TI-7 MathMate was eventually replaced by the TI-10, which features a two-line display.
