# Windows Calculator

**Logic**Level 1

**Step 1**: The windows calculator evaluates that \( \sqrt{4} - 2 = -1.068281969439142 \times 10^{-19} \) which is less than \(0\). So we can conclude that:

\[ \sqrt4 - 2 < 0 . \]

**Step 2**: Add \(2\) to both sides of the inequality to obtain:

\[ \sqrt{4} < 2 . \]

**Step 3**: Since both terms are positive, we can square both sides to obtain:

\[ 4 < 4 \]

In which of these step did I make a flaw in my logic?
