DescriptionA stack-based calculator, with macros.
In a stack-based calculator, parentheses are not used. Values are added to the stack, then operations are performed on the top element(s) of the stack. For instance, 5+3 becomes: 5 (enter) 3 +. 5 and 3 will disappear from the stack, to be replaced with 8. (2+7)*(10-4) becomes 2 (enter) 7 + 10 (enter) 4 - *. The first operation to be computed is addition, so the first operation you type is +,when you have 2 and 7 at the top of the stack. The second operation to be computed is subtraction, so the second operator you type is -, after putting 10 and 4 on the stack. The last operation to be computed is multiplication, so the last operator you type is *.
In this calculator, sequences of operations can be recorded as macros, and played back with a single tap on the touchscreen.
InstructionsTap numbers and operations on the touchscreen. The stack is shown on the top screen. Tap the 'HELP' button for more help.
