Binary Addition and Subtraction

Binary addition is where
for example:
11010
+
01001
When adding 0+1, the answer would be 1. 0+0 would equal to 0. 1+1+1 would equal to 1, and you’d have to carry the 1. So therefore, the answer for that equation would be: 110011. With subtracting, 0-0 would equal to 0. 1-1 would equal to 0. Then with 0-1, you’d carry the one, then subtract.
