Happy 10-24-26! This is the last Pythagorean Triple Day this century, so be sure to celebrate right! 📐😉

I knew about Jerk, but the rest were all new to me!

This is why we need to know math for real life!

If the bill is $30.53 and the “20% tip” says $7.59, we’ve officially added a math scam to dinner.

Because 20% of $30.53 is about $6.11.

And yes, I’m still tipping.

I’m just not letting the receipt negotiate on behalf of my server. 😂

Tipping culture has already gotten weird enough with tablets asking for 25%, 30%, and apparently my firstborn child for handing me a muffin.

Now I’ve gotta pull out the calculator and audit the suggested gratuity too?

If there’s some other subtotal being used to calculate the tip, fine. SHOW ME.

Otherwise I’m doing my own math.

Generous and gullible are two completely different things.

This is a neat clock!

14 MARCH -HAPPY PI DAY 2026❤️🌹♥️

Pi VALUE EXIST IN EVERYWHERE 🌹❤️♥️

The number pi is the reason between the length of a circumference and its diameter. That value is always the same no matter the size of the circle. Mathematically, it is an irrational number, meaning that it cannot be expressed as an exact fraction and its decimal expansion does not end or present a periodic pattern. Their numbers go on indefinitely.

From that property emerges the idea that any finite sequence of digits — such as a date of birth or telephone number — could appear at some point in its decimals. In theory, if the sequence is finite and the decimals are not repeated with a fixed pattern, there is no known mathematical reason that prevents that specific combination from appearing.

However, there's an important nuance: the fact that pi is infinite doesn't automatically imply that it contains all possible sequences. To assert that rigorously one would need to prove that pi is a normal number, that is, its digits are distributed completely evenly and randomly on base 10. To date, pi has not been formally demonstrated to be normal, although computational analyses performed on trillions of digits show a distribution compatible with that hypothesis.

In practice, trillions of decimals of pi have been calculated using advanced algorithms and supercomputers, and within those trillions of numbers already appear. From a probable point of view, the more numbers are calculated, the greater the probability of finding any specific finite sequence.

Happy Pi Day!
