1) For the following find:

a) the diminished radix(9s ) complement and

b) the radix(10s) complements ,

* (437) ₁₀ =

*(14037)₁₀ =

*(101730)₁₀ =

*(5671)₁₀ =

2) Find the 2s complement of the following:

• 1101101 =
• 0111010 =
• 1101000 =

3) Using 10s complement, subtract

• 84701 5143 = 470
• 130471 3671 = 003671
• 5067 84342 =
• 3701 -45785 =

4) Given A = 1010101

B = 1110110

Perform the subtraction, by using 2s complements

• A B =
• B A =
