We are going to document a formula for converting from base 10 to base 2 and back again. We would use 35 as the base 10 value.

To convert 35 to base 2, we would divide 35 by 2 and keep the remainders. eg.

```
35 / 2 = 17 r 1
17 / 2 = 8 r 1
8 / 2 = 4 r 0
4 / 2 = 2 r 0
2 / 2 = 1 r 0
1 / 2 = 0 r 1
```

The base 2 value of 35 is 100011.

To convert 100011 to its base 10 value which is 35, we would multiply each base 2 digit by 2 and the power of their position. e.g.

```
1 * 2^0 = 1
1 * 2^1 = 2
0 * 2^2 = 0
0 * 2^3 = 0
0 * 2^4 = 0
1 * 2^5 = 32
```

Then we would add all the resulting values together.

`1+2+0+0+0+32 = 35`

Hope this helps you simplify the conversion process.
