A mi m’ha fet pensar amb els #explodingDots
Division made easy🤩
Comenzamos con los #ExplodingDots de @jamestanton.
¿Cómo se representan estos números en la "máquina 1<--2"?
La secuencia completa (hasta operaciones con polinomios en Secundaria), aquí: https://t.co/zyisWBHyoB
Can every number be written as a palindrome in some #explodingdots way?
(For instance, 21 equals one 100, negative eight 10s, and one 1.)
For a number N, let N* represent the number with its digits reversed.
If a is a palindrome, prove that it is possible to write N in an #explodingdots way so that
a x N* = (a x N)*
(The product of a palindrome with a number and with its reverse are also reverses.)
Multiply a number and its reverse by 81.
Prove that the two products can be written in an #explodingdots way so that they are the reverse of each other!
What a fabulous lad ... and fabulous Dad for allowing the true fun of learning thrive!
And gotta love them dots!

“Follow the child” can be as easy as helping them go down the rabbit holes of their own choosing.
6yo wanted to know how computers worked so we did some research. He was curios about binary so we pulled up Exploding Dots by @jamestanton.
In <1h he was converting binary to decimal.
It's the final day of Global Math Week 2024.
But math joy, of course, continues all year.
Play with #explodingdots any time with all the resources here

Math truly does transcend and uplift.

Happy Global Math Week 2024 !!
Enjoy the Day #7 Exploding Dots Puzzle

Every number leaves the same remainder upon division by 9 as does the sum of its digits.
E.g. 1213 is 7 more than a mult of 9, as is 1+2+1+3
87 is 6 more, as is 8+7
109 is 1 more, as is 1+0+9
Can you use #explodingdots to explain this rule?
Global Math Week continues! #gmw2024
a) Show that x^3 - 1 is divisible by x -1.
b) Is 48,682,904^906 - 1 a prime number?

Enjoy the Day #6 Exploding Dots Puzzle
@jamestanton @GlobalMathProj
Can you explain this bizarre divisibility rule for the number 7 using #explodingdots?
It's Day 4 of Global Math Week! #gmw2024

It's become a tradition at CAC to celebrate Global Math Week with a song! @cactweets @jamestanton @GlobalMathProj #GlobalMathWeek #ExplodingDots https://t.co/VsEYt9sCgm
In this lopsided Δ each entry sum of the two numbers above, right number doubled.
Interpret each row as a number the #explodingdots way.
Select any two of these nmbrs and divide. Why is the result sure to be another nmbr in the list?
(Other Δ patterns?)

Number Δ:
Each entry = sum of the three numbers above (the one directly above & its two neighbors). Interpret each row as a number the #explodingdots way.
Select any two of these nmbrs. Divide them. Why is the result sure to be another nmbr in the list?
