Chapter 29:Bewildered
Demetri Frost opened the door to his house and paused on the threshold, momentarily doubting if this was indeed his own home. Firstly, loud music was blasting from the speakers. Secondly, his usually odorless home now carried the fragrance of a vanilla-scented bomb explosion. And thirdly, his normally empty and serene living room was a complete mess!
Sitting right in the heart of this chaos, her face buried in a book, was his wife. Unaware of his presence, she was cursing in a manner that would have made a sailor blush.
Casually, he walked over to her and peered over her shoulder, curiosity piqued about what had compelled the typically reserved woman to curse in such a manner. Usually, upon his return, he would find her curled up on the couch with a novel in hand.
If not for laying eyes on her, one would hardly know she was there; she was an expert at being invisible, and this suited him just fine. He cherished the quiet and did not have to regret marrying her.
She stiffened as she felt his closeness but did not move. Turning her head a bit, she looked up at him with wide eyes before quickly turning back to her work. He peered down at the jumble of formulas she had used to solve her assignment and raised his eyebrows.
Without a word, he extended his hand and held hers. Taking the pen from her, he quickly wrote down the correct formula, marking her mistakes.
As he moved closer to finish the entire solution, Nora stood there frozen. She could feel his heat surrounding her and she already had goosebumps all over her.
She felt his other hand move around her waist, and she was even more startled as it settled on her hip. Gently, he nudged her closer to the kitchen island and pointed with his other finger, "Here, this is not how this is calculated. For this function, you need to imagine that you are driving on a curvy road, and you want to know how fast your speed is changing at a specific moment—basically, to calculate change. But if you use this formula..."
Even though Nora remained hyperaware of him, his hand still on her hip, she was even more engrossed in what he was teaching her. This was the most basic problem, but the way he explained it... wow. She was actually understanding this! As he finished solving the entire problem and was about to step back, she quickly grabbed his wrist, peered through the scattered books, and pulled out a few sheets of paper stapled together, pointing at them. "Help me with this, please! I am totally hopeless with all these calculations! I just don't understand why we have to do all these calculations! I just want to start a small business in the future! It's not like I am going to need derivatives and integers for that!"
"Derivatives are essential in understanding rates of change, which is crucial in economics, finance, and decision-making within businesses. They are used in areas like calculating marginal costs, analyzing demand curves, and evaluating investment opportunities. If you want to have your own business, then you need to understand them."
