Same trick will work next year too!

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)

Don't worry it works for all factors of ten. Like 1^0^ = 1

[–] Habahnow@sh.itjust.works 66 points 1 year ago

Took me too long to realize the 0 can be an exponent.

[–] blind3rdeye@lemm.ee 61 points 1 year ago

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.

They'll get complexes

Kind of hard to define but refer to themselves as I?

[–] ilost7489@lemmy.ca 5 points 1 year ago

Sounds pretty complex

Theres no way that a dude that got a girl pregnant at 18 would understand this.

[–] blanketswithsmallpox@lemmy.world 32 points 1 year ago* (last edited 1 year ago) (1 children)

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.

Sucks to be you nerd.

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.

But when you finally get it

[–] ThatWeirdGuy1001@lemmy.world 18 points 1 year ago* (last edited 1 year ago) (11 children)

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 😭

[–] jendrik@discuss.tchncs.de 24 points 1 year ago (2 children)

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.

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

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:

[–] lugal@lemmy.ml 8 points 1 year ago

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"

[–] ShaunaTheDead@kbin.social 8 points 1 year ago

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.

[–] Floey@lemm.ee 7 points 1 year ago

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 + 0

In 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

Good luck trying that in two years.

It's not less of a meme than most of the other posts in this community.

[–] Random_user@lemmy.world 3 points 1 year ago (1 children)

Idiots think posting "funny" pictures are memes.

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

[–] drcabbage@lemmy.ml 12 points 1 year ago

Oh, I get it! I get jokes!
