If your child says “ooh, I want the spicy ones” when she sees “flavor-blasted” goldfish, you have failed as a parent.

(It’s me, I have failed as a parent.)

It's funny, because this is in fact the entire underpinning of differential calculus: changes are small compared to levels.

I'm a day late, but not a hypotenuse short on this one. Why 7/24/25 is (was) a special day, and what it shows us about other special right triangles.

How would you compute 42² + 126² in your head? Spot that 126 = 3 × 42, and the sum becomes 42² + (3×42)² = 10 × 42² = 17,640. A tough-looking problem turns into one quick multiplication—if you catch the pattern. #MentalMath #MathTricks #SumOfSquares

for me, personally, if something happened after something else, it's quite clear it happened because of the something else.
