Use counters to model two integers with different signs whose sum is positive.Explain how you know the sum is positive.

if you add two numbers with different sign , but absolute value of positive number is greater than absolute of negative number , sum will be positive  ex. -4+7=3 I7I GREATER THAN I-4I,   WE SUBTRACT 4 FROM 7 =3    POSITIVE  OR -14 +20 =6 POSITIVE , ABSOLUTE VALUE OF 20 GREATER THAN ABSOLUTE VALUE OF -14
