Now That We Have Passed The Midpoint In The Course

Now That We Have Passed the Midpoint In the Course And Everyone Is F

Now that we have passed the midpoint in the course, and everyone is filled with anxiety, Discussion #4 is designed to lighten the mood and to entertain you. Please watch the video below and let us know your "reaction" in 50 words or more (Was it entertaining? Do you think it's "rigged"? Could you learn to calculate numbers in your head? Do you have any number tricks to share?).

Paper For Above instruction

Having watched the video, I found it both entertaining and intriguing. The presenter’s ability to calculate complex numbers mentally was impressive, though I suspect some tricks or sleight of hand might be involved, raising questions about whether it was "rigged" or genuine. Personally, I enjoy learning mental math tricks, as they boost confidence and cognitive agility. For example, I have a trick for multiplying two-digit numbers ending in 5: multiply the first digits, then append 25. For instance, 47 × 35: (4×3)=12, then write 1225, so 47×35=1645. Watching this video has inspired me to practice such tricks more diligently, as they reveal the fascinating interplay between simple arithmetic and psychology. Overall, it was a delightful distraction from midterm stress, showing the playful side of mathematics, and reminding us of the fun that numbers can provide in everyday situations. Engaging with mental math is not only practical but also enhances problem-solving skills, which are invaluable across various academic and real-world contexts. This experience reinforced that with a bit of practice, many calculations can become swift and impressive, transforming math from a daunting subject to an entertaining challenge.
