# “7 Shocking Truths About Math They Won’t Tell You!”

## On Zero, Negative Numbers, Multiplication & More!

1. The definition of multiplication attributed to Euclid since 1570 is WRONG! (Mis-translated, so gives wrong answers)
2. The western definition of zero is WRONG! (sub-optimal)
3. Debt × Debt = Fortune meme taught is GARBAGE! (Brahmagupta never said that.)
4. Definition of integral exponentiation is WRONG!
5. To teach negative numbers are 'less than zero' is WRONG.
6. Multiplication is NOT repeated addition! (That's an algorithm, so is repeated subtraction.)
7. The Logic of Elementary Math has been LOST! (HINT: It's found in ancient China and India.)
