Here’s a magic trick I’m doing with my students….

1. Pick any number.

2. Multiply that number by -3

3. Add 2

4. Multiply by 5

5. Add 15 times your original number.

Abracadabra…. you’re left with the number 10! (and if you’re not, double-check your math!)

Curious?? How about another one…

1. Pick a number

2. Multiply that number by -4

3. Add 10

4. Multiply by 2

5. Add 8 times your original number

Alacazam…. you’re left with the number 20! (or double-check your math!!)

I guess this is the closest I’ll ever get to Hogwarts!!

Anyone have an idea how it works!??!
