7. Mayans
• First civilization to actively use zero in
equations
• Used zero to create Long Count and yearly
calendars
8. Indians
• First civilization to describe the basic
mathematical properties of zero
• Described
addition, subtraction, multiplication, and
division with, by, to, and from zero
9. Math with Zero!
• 2+0=2
• 5–0=5
• 4x0=0
• 3/0 = ?
Which one of these is not
like the others?
10. The Powers of Zero!
5² = 5 x 5 = 25
5³ = 5 x 5 x 5 = 125
BUT! Why does: 5: = 1?
5: = 5 ….???!!
11. The Powers of Zero (Cont’d)
5² = 5 x 5 = 25
5³ = 5 x 5 x 5 = 125
What about 5³ x 5²?
5³ x 5² = (5 x 5 x 5) x (5 x 5) = 125 x 25 = 3125
there are five 5’s! So: 5³ x 5< = 5⁵
OR!
5³ x 5< = 5=⁺< = 5⁵
12. The Powers of Zero (Cont’d – last slide
on this I swear!)
What about 5³/5<? Well …
5³ = 5 x 5 x 5
5² = 5 x 5 DIVIDING THEM CANCELS TWO 5’s
Leaving you with: 5 or 5¹. So 5³/5< = 5=⁻< = 5;
Returning to our 5: issue: We know 5=/5³ = 5:
5³ = 5 x 5 x 5
5³ = 5 x 5 x 5 125/125 = 1
19. Solution 3: X/0 = Infinity
• Proposed by the Indian mathematician
Bháskara
• Initially rejected by the mathematical
community because of flaws in the proof
• Bháskara made an edit that would become
the basis for quantum mechanics
20. Solution 4: 0/0 = Infinity
• This solution works!
Let’s say 0/0 = 746.345689 So if we multiply
each side by 0
0 x 0/0 = 746.345689 x 0
0=0
Works no matter
what number we
0/0 = -45078932 set 0/0 equal to!
0 x 0/0 = -45078932 x 0
0=0 Therefore 0/0 = ∞
21. Applications of Solution 4
Quantum Mechanics!
Before you look for
an electron, it isn’t in
any one place – it
exists only as a
potential.
So, it, theoretically, is
in an infinite number
of locations at any
time.
22. Human Application
Before you start anything, your speed –
how fast you are moving towards your
goal – is infinite.
