🔢 The Magic of 9️⃣ – It's Like a Fun Trick! 🎩✨

A handy 😏👋 math secret

"Can this number go into that number evenly?" Tricks:

1 = yes it can always go into that number evenly.

2 = If that number is even then yes.

4 = If that number is a three digit number or more, you only need to know if it goes into the last two digits evenly.

5 = If the last digit is a 5 or 0 you are good.

8 = like 4, but you need one more digit.

I skipped some numbers for a reason as they are special:

9 = add up all the digits. If this new number works so does the original. Still unsure? Well keep doing this until you only have one digit left. If that digit is 9 you are good.

3 = like 9 but if you get to one digit the good answers are 3, 6, and 9

6 = just check if it's even and if 3 goes into it.

And that's all our numbers 1 to 9...

What about 7 you ask? What about it?
