ATENÇÃO!!!!



Diferença em
matemática é subtração!!! (conta de menos!)



Qual a diferença
entre 10 e 5?



10 - 5 = 5



Qual a
diferença entre 25 e 12?



25 - 12 = 13



Agora é sua
vez...



Qual a
diferença entre 20 e 11?

















Qual a
diferença entre 65 e 47?















Qual a
diferença entre 30 e 15?
