One line show operator. One line show operandus. One line show traditional display. One line show memory.

Use the keyboard as usual.

Each operation (+, -, x, /) change display AND operandus. So you can press again to apply current operator and NEW operandus to display.

Equal operation (=) change only display. So you can press again to apply current operation and operandus to display.

Simple operations (square root, oposite, inverse) change only display.

M+ add display value to memory. MR pop memory into display.

C clear only display.

AC clear display, operandus, operator (to default =) and memory.

Examples (in parenthesis display value):

1 + 2 x 3 = 6

1 + 2 = 3, = 4, = 5, = 6 ...

1 + 2 + (= 3) + (= 6) + (=12) ...

2 * 2 = 4, = 8, = 16 ...

2 x 2 x (= 4) x (= 16) x (= 256) ...
