Calculation: 1 << 24
Decimal: 16777216
Binary: 1000000000000000000000000
//      ^ 25th position because 1 was shifted 24 times to the left

Calculation: 1 << 16
Decimal: 65536
Binary: 0000000010000000000000000
//              ^ 17th position because 1 was shifted 16 times to the left

Calculation: 1 << 8
Decimal: 256
Binary: 0000000000000000100000000
//                      ^ 9th position because 1 was shifted 8 times to the left

  1000000000000000000000000 = 1 << 24
  0000000010000000000000000 = 1 << 16
  0000000000000000100000000 = 1 << 8
+ 0000000000000000000000001 = 1
  |-------|-------|-------|
  1000000010000000100000001 = 16843009

1 << 8 = 0b100000000 = 256 = 0x100

1 << 16 = 0b10000000000000000 = 65536 = 0x10000

(1 << 8) + (1 << 16) = 0x10100
