I am late to answer these challenge questions.

challenge 1:

1. 1(1) = 10-1 =9

2. 2(22) = 200 – 22=178

3. 3(303) = 3000 – 300=2700 – 3 = 2697

4. 6(7)8(9) = 6000-700=5300 ;80-9=71; the number becomes 5371

5. 77(03)1 = 70000 + (7000 – 30 ) +1 = 70000 +6960+ 1 = 76961

6. 8(01)9(01) = 8(01)/9(01) = (800-1)/(900-1) = 799899
