Remember to include the subtraction sign.KFC the circled numbers.Add all positive integers.Add all negative integers.Lastly, add integers.StrategyExamples:A) -2 + 5 8 (-4)KFCFC-2+ 5+ (-8)+ 49 +(-10)-1Examples:B) 5 8 9 + 4 (-7)KFCFC5+ (-8)+ 416 +(-17)-1FC+ (-9)+ 754+716Examples:C) -7 3 (-8) + 5 + 6 9KFCFC-7+ (-3)+ 519 +(-19)0FC+ 8+ 685+619+ (-9)73+9-19Examples:D) 8 9 (-11) 4 + 6 1 + 6KFCFC8+ (-9)+ (-4)31 +(-14)17FC+ 11+ 686+631+ (-1)94+1-14FC+ 611
