Not a computer scientist, but I assumed that all CPUs worked by getting the numbers first, then doing the thing on them (add, shift etc). At least that is how assembly looked like to me.

Depending on the CPU, the fetched instruction may encode both the operation and one or more of the operands, (which may be an immediate value, a direct or indirect memory location (with absolute or relative address), or a register).
