Here are the binary addition problems you listed:

1.

```
10010
+ 1100
-------
11110
```

Let's verify:
```
10010
+ 1100
------
11110
```

Step-by-step:
- Rightmost column: 0 + 0 = 0
- Next: 1 + 0 = 1
- Next: 0 + 1 = 1
- Next: 0 + 1 = 1
- Leftmost: 1 + 0 = 1

So: 10010 + 1100 = 11110 ✔ Correct.

2.

```
1011101
+ 1000000
---------
10011101
```

Addition:
```
1011101
+ 1000000
--------
10011101
```

Let’s add step by step (right to left):

- 1 + 0 = 1
- 0 + 0 = 0
- 1 + 0 = 1
- 1 + 0 = 1
- 1 + 0 = 1
- 0 + 1 = 1
- 1 + 1 = 10 → write 0, carry 1
- Carry 1 → 1

Result: 10011101 ✔ Correct.

3.

```
10011
+ 111101
--------
10010000
```

Align properly:
```
10011
+111101
-------
10010000
```

Now add:
```
10011
+111101
-------
10010000
```

Right to left:
- 1 + 1 = 10 → write 0, carry 1
- 1 + 0 + 1 = 10 → write 0, carry 1
- 0 + 1 + 1 = 10 → write 0, carry 1
- 0 + 1 + 1 = 10 → write 0, carry 1
- 1 + 1 + 1 = 11 → write 1, carry 1
- 0 + 1 + 1 = 10 → write 0, carry 1
- Carry 1 → 1

Final result: 10010000 ✔ Correct.

4.

```
10011001
+ 100111
----------
11000000
```

Align:
```
10011001
+ 0100111
----------
11000000
```

Add:
```
10011001
+ 0100111
----------
11000000
```

Step-by-step:
- 1 + 1 = 10 → 0, carry 1
- 0 + 1 + 1 = 10 → 0, carry 1
- 0 + 1 + 1 = 10 → 0, carry 1
- 1 + 0 + 1 = 10 → 0, carry 1
- 1 + 0 + 1 = 10 → 0, carry 1
- 0 + 1 + 1 = 10 → 0, carry 1
- 0 + 0 + 1 = 1
- 1 + 0 = 1

Wait — let's write it with proper alignment:

```
10011001
+ 100111
---------
11000000
```

Actually, 100111 is 7 bits, so:
```
10011001
+ 0100111
---------
11000000
```

Now add:

Positions (from right, index 0):
- Bit 0: 1 + 1 = 10 → 0, carry 1
- Bit 1: 0 + 1 + 1 = 10 → 0, carry 1
- Bit 2: 0 + 1 + 1 = 10 → 0, carry 1
- Bit 3: 1 + 0 + 1 = 10 → 0, carry 1
- Bit 4: 1 + 0 + 1 = 10 → 0, carry 1
- Bit 5: 0 + 1 + 1 = 10 → 0, carry 1
- Bit 6: 0 + 0 + 1 = 1
- Bit 7: 1 + 0 = 1

So result: 11000000

But wait — that would be:
- Bit 7: 1
- Bit 6: 1
- Bits 5–0: 000000 → 11000000

Yes, matches.

So: 10011001 + 0100111 = 11000000 ✔ Correct.

5.

```
1100001
+ 101111
---------
11110010
```

Align:
```
1100001
+ 0101111
---------
11110010
```

Add:
```
1100001
+ 0101111
---------
11110010
```

From right:
- 1 + 1 = 10 → 0, carry 1
- 0 + 1 + 1 = 10 → 0, carry 1
- 0 + 1 + 1 = 10 → 0, carry 1
- 0 + 1 + 1 = 10 → 0, carry 1
- 0 + 0 + 1 = 1
- 1 + 1 = 10 → 0, carry 1
- 1 + 0 + 1 = 10 → 0, carry 1
- Carry 1 → 1

So: 11110010 ✔ Correct.

6.

```
1001100
+ 1100101
----------
10110001
```

Align:
```
1001100
+ 1100101
---------
10110001
```

Add:
- 0 + 1 = 1
- 0 + 0 = 0
- 1 + 1 = 10 → 0, carry 1
- 1 + 0 + 1 = 10 → 0, carry 1
- 0 + 0 + 1 = 1
- 0 + 1 = 1
- 1 + 1 = 10 → 0, carry 1
- Carry 1 → 1

So: 10110001 ✔ Correct.
