Same trick will work next year too!
2^1
i thought they meant 20 + 1, but this makes way more sense

Brilliant, now I wonder what ages this works for, I figured only 1 and 2, but then I realised we could write the father’s age in other bases…
1 = 2^0 (20 b10)
2 = 2^1 (21 b10)
3 = 3^1 (31 b7 = 22)
6 = 6^1 (61 b4 = 25) if they are lucky the grand father will be 61 that year :-D
8 = 2^3 (23 b12 =27)
9 = 9^1 (91 b3 = 28)
14 = 14^1 (141 b4 = 33)
You have mistakes in a few of those. The number “61” doesnt exist in b4. 25b10 in b4 is “121”.
Similar problem with 91b3 and 141b4.
Indeed, I was so focused on the algebraic side I didn’t even think about it :-D
I was computing 6*4+1=25
And the following year as well!
Poor kid going from 2 to 8 in 1 year.
You mean 2 -> 4?
2^2 = 4
Ahh yes your right, my bad. I was thinking the power was equal to her age but it is actually -1 her age. I was doing 2^3 when it should have been 2^2. I guess that is what I get when I don’t show my work. Dang math teacher was right.
And I thought you were making a follow-up joke to mine…
Haha, no.
Having kids at 19
Bruh
And pregnant at 18

Don’t worry it works for all factors of ten. Like 10 = 1
Took me too long to realize the 0 can be an exponent.
Ah yes. How fitting for a young new person in the world. A reminder that 2°C of warming above the pre-industrial mean would be catastrophic, but also is a good lower-limit of what to expect based on current intentions.
My kids are √-1
Imaginary kids are better
They’ll get complexes
Kind of hard to define but refer to themselves as I?
Sounds pretty complex
they live in a different dimension
Theres no way that a dude that got a girl pregnant at 18 would understand this.
I know plenty of smart people pretending to be Winnie the Pooh while elbow deep in honey pots. Just because you weren’t fucking doesn’t mean other nerds weren’t lol.

What?! Impossible to start a family at 18 and also enjoy mathematics?
Not everyone who has unprotected sex at 18 (or with an 18 yr old) is some numbskull just going at it for unscrupulous pleasure.
(As another reply also pointed out: the pun was crafted by the OP’s dad, not the 1yr-old’s dad; and OP could be the child’s mum or dad)
He probably didn’t. Her dad (the grandpa) made the balloons.
so it was obviously the kid’s mom turning 20 then 😉
Damn, that took me waaay too long to get…
Not my brightest moment… 😅
But when you finally get it
I know I’m bad at math but I don’t understand how 2x0=0 but 2^0=1
How are they different answers when they’re both essentially multiplying 2 by zero?
Someone with a bigger brain please explain this
Edit: I greatly appreciate all the explanations but all they’ve done is solidify the fact that I’ll never be good at math 😭
subtracting one from Exponent means halving (when the base is two):
2⁴ = 16 2³ = 8 2² = 4 2¹ = 2 2⁰ = 1
It’s a simple continuation of the pattern and required for mathemarical rules to work.
This is confidently wrong.
3^0 is also 1. 2738394728^0 is also 1.
Edit: just saw that technically you’re correct - sure.
IF base 2, Exponent reduction equals to halving - dividing by 2.
For x^y reducing y by one is equal to dividing by x, then we have the proof it always works.
But that’s because for 3 the sequence is dividing by 3 not 2.
81, 27, 9, 3, 1, 1/3, 1/9, etc.
3^4, 3^3, 3^2, 3^1, 3^0, 3^(-1), 3^(-2), etc.
You’re not always halving, but the method is the same and it sometimes helps people understand the concept more easily.
0 is the neutral element for addition. This is why when we have a number then 0 + number = number (0 doesnt change the value in addition) and why 0 x number = 0 (if you add a number 0 times you will have 0). (Multiplication is adding one of the numbers to itself the number of times designated by the second number)
The same way 1 is the neutral element for multiplication. This is why when you have some number then 1 * number = number. This is also why number^0 = 1 (if you never multiply by a number you are left with the neutral element. It would be weird if powering by 0 left you with 0 for example because of how negative powers work)
This is the level 1 answer.
The level 0 answer is that it is this way because all of mathematics is a construct designed to ease problem solving and all people collectively agreed that doing it this way is way more useful (because it is)
Choose which one you want
Fuck me this is the only one I understand 😭
Easiest explanation I can think of using the division law for exponents:
Since we can use any number for the initial fraction, as long as the denominator is the same as the numerator, any number to the zeroth power is equal to 1. In general terms, then, for any number, x:
You can think of 1 as the “empty product” (or the “neutral element of multiplication” if you want to be fancy). 2^x means you have x factors of 2. If you have 0 factors, you have the “empty product”
I see other people have posted good explanations, but I think the simplest explanation has to do with how you break down numbers. Lets take a number, say, 124. We can rewrite it as 100 + 20 + 4 and we can rewrite that as 1 * 10^2 + 2 * 10^1 + 4 * 10^0 and I think you can see why anything raised to the 0th power has to equal 1. Numbers and math wouldn’t work if it didn’t.
I like to think of it this way:
2^3 is the same as 2 x 2 x 2.
But you can arbitrarily multiply by as many 1s as you want because 1 has the identity property for multiplication.
So we can also write 2^3 as 2 x 2 x 2 x 1 x 1.
2^2 as 2 x 2 x 1 x 1.
2^1 as 2 x 1 x 1.
2^0 as 1 x 1 or just 1.Multiplying a number by another number is the same as adding a number to itself that many times. And 0 is has the identity property for addition, so similarly:
2 x 3 = 2 + 2 + 2 + 0 + 0
2 x 2 = 2 + 2 + 0 + 0
2 x 1 = 2 + 0 + 0
2 x 0 = 0 + 0In addition to the explanation others have mentioned, here it is in graph form. See the where the graph of 2^x intersects the y axis (when x=0):
https://people.richland.edu/james/lecture/m116/logs/exponential.html
This also has some additional verbal explanations:
http://scienceline.ucsb.edu/getkey.php?key=2626
The simplest way I think of it is by the properties of exponentials:
2^3 / 2^2 = (2 * 2 * 2) / (2 * 2) = 2 = 2^(3-2)
Dividing two exponentials with the same base (in this case 2) is the same as that same base (2) to the power of the difference between the exponent in the numerator minus the exponent in the denominator (3 and 2 in this case).
Now lets make both exponents the same:
2^3 / 2^3 = 8/8 = 1
2^3 / 2^3 = 2^(3-3) = 2^0 = 1
Its not the same. And theres proof, why.
Thanks, I couldn’t even tell what the image was about math. I thought a dirty joke was hidden somewhere involving the 0. Didn’t realize it was small and floating above on the right so people would immediately realize it’s a power lol. Many people hide clever things but I always approach them in the wrong way lol.
2^0 isn’t multiplying by zero. Considering this law: 2^a / 2^b = 2^(a-b)
it’s obvious why 2^0 = 1
If a=b you’re dividing by the same number resulting in 1.Unfortunately, I cannot explain/prove the first law though.
The first rule is just simple division:
(2x2x2x2) / (2x2) =
(2/2) * (2/2) * 2 * 2=
1 * 1 * 2 * 2 =
2 * 2 =
4
Writing in terms of powers:
(2^4) / (2^2) =
(2^(4-2)) =
(2^2) =
4
The two bottom 2’s “cancel out” (really they just divide into one another to make 1’s) two of the top 2’s and you’re left with two top twos.
Good luck trying that in two years.
That happened

I don’t get it.
2⁰=1
I still don’t get it.
The 2⁰ looks like 20 (for the 20yr old’s birthday) but when you calculate 2 to the power of 0 it’s equal to 1 (which is for the baby’s birthday). It’s a math joke, hope that helps
Oh, I get it! I get jokes!
2^0 =1^1
That’s not a meme.

True
Idiots think posting “funny” pictures are memes.
They are either part of the “everything is a meme” bullshit, or they don’t care whether the crap they’re posting is a meme.
Both crowds will complain that they’re not posting to other communities because they’re “dead”. Neither group sees the irony.
In the end, these idiots are looking for upvotes and have found the community of other idiots who will upvote anything in their feed without a care of where it’s posted. This group of idiots can go back to reddit.
It’s not less of a meme than most of the other posts in this community.
It’s been a while, but I think I remember this one. Lim 1/n =0 as n approaches infinity. Let x^0 be undefined. For any e>0 there exists an n such that |x^(1/n) -1| < e. If you desire x^(1/n) to be continuous at 0, you define x^0 as 1.
E2a: since x^(1/n)>1, you can drop the abs bars. I think you can get an inequality to pick n using logs.
Simpler: x^1 = x, x^-1 = 1/x
x^1 * x^-1 = x^0 = x/x = 1.
Of course, your explanation is the “correct” one - why it’s possible that x^0=1. Mine is the simple version that shows how logic checks out using algebraic rules.
Of course you both assume x =/= 0 though.
Where are my programmer buddies? 🤘

tbh not as bad as i expected but still
