Question

Add the following base 2 numbers 1000101 and 10011

Answer 1

remember with base 2 numbers there are only 2 digits 0 and 1

so 1 + 1 = 10 in base 2

1000101 (69)
10011 (19)
---------
1011000 (88)


and to check

\[88 = 1 \times 2^6 + 0 \times 2^5 + 1 \times 2^4 + 1 \times 2^3 + 0 \times 2^2 + 0 \times 2^1 + 0 \times 2^0\]

hope it helps
