Here are the main logic components:

• appendNum(): Adds digits to the current expression.
• appendOp(): Appends operators while ensuring no invalid sequences.
• appendDot(): Adds a decimal only if the current number segment doesn’t already contain one.
• calculate(): Sanitizes and evaluates the expression.
• clearOne(): Deletes the last character.
