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?
