How to perform multiplication in 8085?

In 8085
There is no direct instruction to perform multiplication. We need to perform repetitive addition to get the result of the multiplication. In each step we are decreasing the value of B and multiply with the previous value of B. We are repeating these steps until B reaches 1. and B – 1 to 0.

Should I learn 8085?

In the first place, you'd better learn how to write 8085 if you expect to use it. Assembler, especially for old 8-bit microprocessors, is not something you can just take canned software and patch in. In the second place, exactly what are you using for numbers? The 8085 has an 8-bit bus and can use registers as 16 bits.
