binary addition

Answer 1

First line up all the digits:

0101
0100
0010
1010
1110
-----

Next add column by column, just like normal decimal addition, from right to left.
The first (right-most) column adds to 1, so write a 1.

0101
0100
0010
1010
1110
-----
---1

The second column adds to 3, which is represented in binary by 11, so it is a 1 with a carry of 1.
0101
0100
0010
1010
1110
-1---
--11

The next digit adds up to 4, including the carry, which is a 100, so, by adding a digit on the left to allow for the carry, we have:

00101
00100
00010
01010
01110
1-----
--011

The next digit adds up to 2, or 10 in binary.

00101 (5)
00100 (4)
00010 (2)
01010 (10)
01110 (14)
2-----
-0011 (35)

The carry of 2 (10 in binary) gives 100 to the left, or
100011 in binary,or
35 in decimal
