Why 10|5 =15 but 15|5 =15?

Question

Help

Answer 1

10 in binary is represented as 1010 and 5 in binary is represented as 0101

We already knew that, 1 or 0 is always 1

So, 1010
0101
__________
1111 => 15(decimal representation)

Similarly, 15 => 1111
5 => 0101
Which results in 15 (1111)

Answer 2

Binary

1010(10) 1111(15)
0101(5) 0101(5)
---------- ---------
1111(15) 1111(15)
