use binary addition to bsolve the following decimal summations

1)4base10+3base10

In binary, the digits are either 0 or 1, so we add the numbers digit by digit based on the following rules:

0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 0 (with a carry of 1)

Here's how we convert 4 and 3 to binary:

4 = 100
3 = 011

Now we add them:

100
+ 011
-----
111

So, 4 + 3 in binary is 111.
