In the main memory, we found the values in the following locations

Address $0100$

Address $0$x$101$

Address $0102$

Address $0103$

B$9$

A$5$

$2A$

$1F$

For question $1$ and $2,$ I expect to see a MARIE instruction word, followed by the address

If addresses $102$ and $103$ represent a single MARIE instruction $("$Use Big Endian$),$ what instruction does that represent?

If addresses $102$ and $103$ represent a single MARIE instruction $("$Use Little Endian$),$ what instruction does that represent?

If the address $100$ represents a signed integer, is that number positive or negative?
