    Flip rule: x% of y = y% of x (= xy/100) Want to simplify your mental calculations? Here's a handy hack: x% of y is equivalent to y% of x. This means that 12% of 50 is the same as 50% of 12. #MathHack #SimplifyCalculations

    💥 Think the Basel problem is “solved”? Think again. I just reframed it using the zero pattern of sin(x)/x—and it clicks in a way Euler never wrote down. \sum_{n=1}^{\infty} 1/n^2 = \pi^2/6, seen through a fresh lens. 🧠✨ #MathHack #BaselProblem #EulerWho #MindBlown

    Teacher hack…hot glue magnets to the back of base ten blocks so you and students can use them on the whiteboard and everyone can see them. Grade 1’s are learning to represent numbers in different ways #grade1 #room116 #mathhack
