nt a $=-48$;

int b $=63$;

int c $=-41$;

int d $=$ a $+$ b $+$ c $-19=$ a $+$ b $+$ c $+(-19)$;

here is an example with other numbers :int d $=$ a $+$ b $+$ c; $2$F$1$B $3$FAO $2$F$2$F $3$FBO $2$FFB $3$FCO $1$AA$01$BB$01$CCO $5$DAB $5$DDC $3$DD$0$ C$000$

pls run it through Brookshear Emulator and also here is some key info

Op$-$Code Operand Description

$1$ RXY LOAD the register R with the bit pattern found in the memory cell whose address is XY

$2$ RXY LOAD the register R with the bit pattern XY

$3$ RXY STORE the bit pattern found in register R in the memory cell whose address is XY

$40$RS MOVE the bit pattern found in register R to register S

$5$ RST ADD the bit patterns in registers S and T as though they were two's complement representations and leave the result in register R R $=$ S $+$ T

$6$ RST ADD the bit patterns in registers S and T as though they represented values in floating point notation and leave the floating point result in register R

$7$ RST OR the bit patterns in registers S and T and place the result in register R

$8$ RST AND the bit patterns in registers S and T and place the result in register R

$9$ RST EXCLUSIVE OR the bit patterns in registers S and T and place the result in register R

A R$0$X ROTATE the bit pattern in register R one bit to the right X times. Each time the low order bit is placed at the high order end.

B RXY JUMP to the instruction located in the memory cell at address XY if the bit pattern in register R is equal to the bit pattern in register $0.$ Otherwise, continue with the normal sequence of execution.

C $000$ HALT execution
