We want to get a 2-digit number with the given properties, we will see that the number is 52
We can simply write it as:
a*10 + b
Where a and b are two integers from 0 to 9, such that a is the "tens digit" and b is the "ones digit"
Now we know that our number must have 5 tens, so a = 5.
And 3 less ones than tens, so: b = 5 - 3 = 2
Then the number is:
5*10 + 2 = 53
