Hello Niklas,

first of all, you need to understand how our numbers are coded.
When you see "8604", you have:
- 8 x1000
- 6 x100
- 0 x10
- 4 x1
Because we use the base "10".
so 8000 + 600 + 0 + 4 = 8604

In binary (base 2), with 0110 1010, you have:
- 0 x128
- 1 x64
- 1 x32
- 0 x16
- 1 x8
- 0 x4
- 1 x2
- 0 x1
Total = 64+32+8+2 = 106 in decimal.
