Subtract $\frac{i}{1}$ from $1$ to get $\frac{-i+1}{1}$.

Step 1: Write $1$ as a fraction by putting $1$ in the denominator.

Step 2: To subtract expressions with the same denominators, we subtract the numerators and write the result over the common denominator.

Add $\frac{-i+1}{1}$ and $i$ to get $\frac{1}{1}$.

Step 1: Write $i$ as a fraction by putting $1$ in the denominator.

Step 2: To add expressions with the same denominators, we add the numerators and write the result over the common denominator.
