The five numbers add up to 10, so the first three numbers add up to 10 - 8 = <<10-8=2>>2.
The third number is 0, so the first two numbers add up to 2 - 0 = <<2-0=2>>2.
The first and second numbers are equal, so they are both 2 / 2 = <<2/2=1>>1.
The fourth number is double the first number, so it is 2 * 1 = <<1*2=2>>2.
The fifth number is 8 - 2 = <<8-2=6>>6.
Thus, Brad’s zip code is 11026.
