### PEEK & POKE math (?? +256 ??)

Posted:

**Mon Jan 15, 2018 4:20 pm**This must be really Obvious!!!!! But it is NOT computing between the ears. (or on paper).

Problem: why do you add 256 to the low byte decimal before multiplying by the high order decimal?

using a hex calculator there is no need for any additon.

and it is not that i can't get the right values to poke in, or peek at...........[here is where we loose everyone]....because i can.

It is that i just wish to use the simple calculator, manually. and follow the process. make sense ?

Okay. Why do you add 256 (ZX81 Basic add 256)?
