@Ankit006. I want to get the value of the previous calculation: Calculation 2(which is 4 in my example) and add it to my new calculation. by pressing an operand button,
that is to say;
when i navigate to calculation 2 and press ‘+ 8’ button, my screen should start a new calculation that reads 4 + 8
which is 4(grabbed from the value from the recent calculations: calculation 2)
and the new ‘+ 8’ that i have pressed
