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

The given probles are

and

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

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

i think it is 70

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
