in the semi-permanent memory (e.g.,
1 5 0 Ç +). Semi-permanent
means the value is cleared when the
calculator is turned off.

Ç – Ç +

(M-)

- Subtracts a

value from the semi-permanent
Memory (e.g., 1 5 0 Ç – Ç

+ subtracts 150 from the memory).

Ç =

(MR)

- Recalls Memory value

(e.g., if 150 has been stored in Memory,
pressing Ç = will display 150).

Ç o

(MC)

- Clears Memory value.

Entering Square or Cubic

To label a dimension as “Square” or
