You should use a mechanism called persistance of vision for interfacing multiple seven segment displays. here is tutorial for mulplexing displays using 8051 microcontroller. http://www.shree-electronics.com/interfacing_multiple_7_segment_displays.htm
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.

Writing a hex program for the 8051 microcontroller on an 8085 microprocessor is not directly feasible, as they are based on different architectures and instruction sets. The 8051 uses its own assembly language and has features like built-in I/O ports and timers that are not present in the 8085. However, you can create a similar program in 8085 assembly language that performs equivalent tasks, keeping in mind the differences in hardware capabilities and instruction sets. You would need to carefully translate the logic and functionality from the 8051 program to suit the 8085 environment.

Writing a program for the 8051 microcontroller can be straightforward, especially with a basic understanding of assembly language or C. The development typically involves setting up an integrated development environment (IDE) like Keil or SDCC, where you can write, compile, and debug your code. The program structure includes initializing registers, defining memory locations, and using specific instructions for operations. Once written, the program can be simulated and uploaded to the microcontroller for execution.

The maximum program memory capacity of the 8051 microcontroller is 64 KB. This limitation arises from its 16-bit address bus, which allows it to address a maximum of (2^{16}) (or 65,536) memory locations. Each memory location corresponds to one byte, hence the 64 KB capacity for program memory. This design constraint is inherent to the architecture of the 8051.
