Question

Draw and write to explain how these two problems are different 35-15=. And 43-26=.

Answer 1

35-15 is 20. and 43-26 is 17. These two are different because you are regrouping in the 2d problem, as in the first, you just subtract. 

Answer 2

The given probles are

`35-15` and
`43-26`

Their main difference is about their results the first problem equals 20 and the second one equals 17. So, the difference between problems is 3 units.

Showing the math, we have

`35-15=20`

`43-26=17\\`

`20-17=3`

So, basically, these problems are different because they have similar operations but with different numbers, which give different results.
