When inputs are A$=1110,$ B$=1110,$ M$=0,$ Outputs S$=1100,$ V$=0.$ The operation is $(-2)+(-2)=-4$

When inputs are A$=0101,$ B$=0011,$ M$=0,$ Outputs S$=1000($decimal $8),$ V$=1.$ The result is valid because $5+3=8.$

When inputs are A$=0101,$ B$=0011,$ M$=0,$ Outputs S$=1000($decimal $-8),$ V$=1,$ the sum is invalid. because overflow occured.

When inputs are A$=1001,$ B$=1010,$ M$=0,$ Outputs S$=0011,$ V$=1.$ The operation negative $+$ negative $=$ positive is invalid because V$=1$
