FWIW, here’s my take—as someone who loves music & is a Jew Excellent: Macklemore loudly & publiclycalling for Palestinian rights Excellent: Musicians rallying behind his call & dropping out of the tour in solidarity Bad: Sheeran’s promoter dropping Macklemore Bad: Macklemore’s Jewface
The rapper Macklemore wearing Jewface—the side profile picture in particular shows the typical highly antisemitic representation of Jews, eg a huge hooked nose and beard. 

Sarah Silverman defines Jewface as: “when a non-Jew portrays a Jew, with the Jewishness front and center—often with makeup, or changing of features, big fake nose, all the New York-y or Yiddish-y inflection.”

Yep. If you assign A = 9, B = 18, C = 27, et cetera [so essentially the multiples of 9] we get: J = 90 E = 45 S = 171 U = 189 S = 171 Total = 666 If you torture the numbers long enough, then you can make them confess to almost anything

This shortcut is valid for all 6-digit numbers, with a slight caveat. To show the caveat, let's use it to find 857,853 days after Thursday: 853 - 857 = - 4 days after Thursday (🤨❓) This result should be thought of as 4 days before Thursday or Sunday. So, 857,853 days after Thursday is Sunday ✅
Six-Digit Number Calendar Shortcut

Example:

What day of the week will it be 132,135 days after Tuesday?

Shortcut:

135 [last three digits] - 132 [first three digits] = 3

3 days after Tuesday = Friday [Answer]

Now It's Your Turn!

What day of the week will it be 254,256 days after Monday?

I'm glad someone else is enjoying numbers as well! Just as a reminder for your journey, though: Years like 2100, 2200, and 2300 are no longer leap years in our current Gregorian calendar because a year ending in 00 has to be a multiple of 400 to be considered leap Best of luck in your travels! :)

Three Different Ways to Multiply 18 by 35: Which one do you prefer? Let me know in the comments! #MathChat #MathsChat #MathSky #MathsSky #Mathematics #Multiplication
Three different ways to show that 18 times 35 is 630:

Method 1 is the traditional algorithm involving carrying and adding.

Method 2 is rewriting 18 as 20 - 2 then applying the distributive property to get 700 - 70 = 630.

Method 3 is imagining an 18 by 35 rectangle, cutting it into two 9 by 35 rectangles, and rearranging them to a 9 by 70 rectangle which leaves the total area of 630 unchanged.

Which method did you prefer?

Would you rather memorize ten formulas or just three? Also, keep in mind that this is just for the basics of kinematics and there are even more physics topics with their own sets of formulas! #MathSky #MathsSky #MathChat #MathsChat #Mathematics #Algebra
Red Title: "Dear Students, this is why we learn algebra!"

On the left-hand side, we see the minimum of TEN kinematics formulas you'd have to memorize if you cannot rearrange equations. On the right-hand side, we see the 3 usually memorized kinematics formulas [along with a clarification that the last one can technically be derived from the previous two by solving for time in the second then substituting into the first and simplifying]. Uniform acceleration is assumed in both cases.

In triangle ABC, M is the midpoint of line segment BC & line segment AM is perpendicular to line segment BC. Given that line segment AM has length 6 centimeters and line segment BC has length 7 centimeters, what is the perimeter of triangle ABC in millimeters rounded to the nearest whole number?

Nice! There's even an elegant way to explain this "trick" visually. While the visual I've shown below technically only proves that the "trick" works for the 35² = 1225 case, similar visuals can indeed be made for all natural numbers ending in 5. I hope you enjoy it! #Mathematics #MathChat #MathsChat
An image showing that a 35 by 35 square can be cut into a 30 by 30 square, two 30 by 5 rectangles, and a 5 by 5 square. The first three pieces can then be rearranged to form a 30 by 40 rectangle, thus showing that 35² = 30 × 40 + 25 = 1225.

A Timezone Inaccuracy from 1% Club UK Due to DST, this question has TWO answers. We could also start 2025-10-25 23:00:00 UTC [midnight October 26 in London & 7 PM October 25 in New York] and add 5 hours to get 2025-10-26 04:00:00 UTC [midnight October 26 in New York, but 4 AM October 26 in London].
Question: If it's midnight in London when it's 7 PM in New York, what time is it in London when it's midnight in New York?

Answer from the show: 5 AM

Actual answer due to DST: Either 5 AM or 4 AM

An example for 4 AM: Start from October 25th 2025, 23:00 UTC and add 5 hours

Long division puzzle where 2025 is being divided by a two-digit divisor to get a quotient with a three-digit integer part and with one digit after the decimal point.

To tell if a number is divisible by 3, you can just add the digits. 2 + 4 = 6 [which is divisible by 3], so 24 is divisible by 3. 1 + 8 = 9 [which is divisible by 3], so 18 is divisible by 3 as well. 4 + 7 = 11 [which is NOT divisible by 3], so 47 is NOT divisible by 3. Hope this tip is useful! :)

While I don't really buy into numerology, there is indeed a system for that. If you start at A = 49, B = 50, C = 51, and so on up to Z = 74 then the phrase "DONALD TRUMP" would coincidentally add up to 666. Also, the final Z = 74 happened to match his age in 2020. Do with that info what you will

√6724 must be between 80 and 85 since 80² = 6400 and 85² = 7225. That means, if 6724 is a perfect square, then √6724 would be 82 [since the only digits which give a last digit of 4 when squared are 2 & 8]. Verifying our assumption shows 82² = 2² × 41² = 4 × 1681 = 6724 as desired. Thus, √6724 = 82.
