What would happen if you have 8 fingers?
If we had eight fingers, this would be written as $104,480. The world population right now is about 7.2 billion people. In base 8 world, this would be written out as about 66,000,000,000 or 66 “billion”, that is, 66 times eight raised to the ninth power, just as a billion in our system is ten raised to the ninth power.
What if humans had 12 fingers?
Yes. We would almost certainly have a 12 digit (base-12) math system if our fingers had 12 digits. Some of the oldest known civilizations have used a base-12 system regardless of finger counting. 12 is a useful number for simple math operations.
Is it a coincidence that we have 10 fingers?
Ask an evolutionary biologist, however, and you’re likely to get a much simpler answer: We have 10 fingers and 10 toes because, somewhere in our species’ past Darwinian wanderings, those numbers gave us an evolutionary advantage. Had events tumbled differently, we might have eight fingers and twelve toes.
Do we use base 10 because we have 10 fingers?
Originally Answered: Why did we adopt a ten digit system in mathematics? When you learned to count as a child, you counted on your fingers. Therefore 10 is a very natural base to use. The ancient Babylonians actually counted differently than we do – they used their knuckles to count – not just fingers.
Why do cartoon people have only 4 fingers?
Advertisement: Why do so many cartoon characters only have four fingers? Simple: a four-fingered hand is SO much easier to draw than a five-fingered hand. Plus, it simplifies the design of the hand in the same way the rest of the body is simplified.
What if humans had four fingers?
Suppose we lived in a world in which humans evolved to generally have four fingers on each hand, instead of five. It’s pretty likely that we would have adopted an octal, or base eight, system, using powers of eight instead of powers of ten. The octal number 10 represents the number 8 in decimal.
What is the 6th finger called?

Can you have 6 fingers?
Six fingers or toes: The presence of an extra sixth finger or toe, a very common congenital malformation (birth defect). This condition is called hexadactyly. The word hexadactyly literally means six digits.
Why do humans have five toes?
In fact, the ancestor of all modern tetrapods — mammals, reptiles, amphibians and birds — had five digits on each of its four limbs back in the Devonian period, 420 to 360 million years ago. Essentially, we have five digits because our ancestors did.
Why is thumb not a finger?
Your thumb is different from your fingers. Your fingers have two joints and three bones called phalanges or phalanxes. A thumb only has one joint and two phalanges.
What age do kids count to 10?
The average child can count up to “ten” at 4 years of age, however it is normal for children to still be learning to count to 5 while others are able to correctly count to forty.
What would happen if we use base 12?
Not only does counting in base-12 allow us to have nicer numbers in division as well as recurring patterns in multiplication, it also paves a smoother path for children to learn basic multiplication.
