How to convert base 2 to decimal?
Convert abcd base 2 to decimal
abcd base 2 = d + c(2^1) + b(2^2) + a(2^3)

Therefore,

1111 base 2 = 1 + 1(2^1) + 1(2^2) + 1(2^3) = 1 + 2 + 4 + 8 = 15
1000 base 2 = 0 + 0(2^1) + 0(2^2) + 1(2^3) = 8
1100 base 2 = 0 + 0(2^1) + 1(2^2) + 1(2^3) = 4 + 8 = 12
1001 base 2 = 1 + 0(2^1) + 0(2^2) + 1(2^3) = 1 + 8 = 9

Add them all up: 15 + 8 + 12 + 9 = 44 (which is a decimal).
Convert 44 back to base 2 (also called binary).
Keep on dividing 44 by 2
22 R 0
11 R 0
5 R 1
2 R 1
1 R 0
0 R 1

44 base 10 = 101100 base 2
