Answer 1

Answer:

hope it helps , its a hint. try it seeing this , sorry

Explanation:

A = 10

B = 11

C = 12

D = 13

so, 476A in is actually 476(10) & D2B9 is actually (13)2(11)9

so let's subtract.

476(10) - (13)2(11)9 = -1(12)89 = -1C89.

or do by parts. u'll understand better.

13 - 4 = 9

20 - 7 = 13

11 - 6 = 5

9 - 10 = -1.

so, 9 goes in unit place. 9 - 1 in tens place. 13 - 1 in hundreds place. & 1 in first place. ok?
