How is 17 + 26 different from 36 + 53? explain ( this is regrouping lesson)

17+26 is different from 36+53 by if you add 17+26 the sum would be 43. And if you add 36+53 the sum would also be 89. So that means the way how they are  different is that the 17+26 and 36+53 has different kinds of sums. They have different kinds of sums because you are different numbers.
