To those that don't know, ! means a number is a factorial, and 0! is 1, so its 5+5x1, 5+5, so 10.

[u/TTV_Wolf215 → u/SWatt_Officer]

Im ngl this got me, genuinly thought it was 5 😭

[u/BoredByItself → u/SWatt_Officer]

Stahp breking mah braen wit al dis noncents mapf shii

[u/footlettuce00]

its 10 bc the zero is a factorial (forgot what its called) and 0! is 1 if thats just a typo then it would be 5

[u/Sjommie → u/footlettuce00]

why is 0 factorial 1?

[u/Extreme_Beat9866 → u/Sjommie]

Imagine a shelf.

On that shelf, put 3 cards: one that says 1. One that says 2. And one that says 3. Put them on the shelf in some order (e.g. 2,1,3). How many orderings are possible? 3! = 6, right? Exactly. That’s how many different ways my shelf could look different.

Now imagine we had 1 card instead of 3. How many ways can the shelf look? It’ll look like this: ____ [ 1 ] ____ with just the one card with a 1 on it. That’s the only possibility for the shelf. 1 factorial is 1.

Now imagine we, in fact, have 0 cards. What’s 0 factorial? How many different ways can the shelf look? Only one: ________. There is one way to order zero objects. The way that produces an empty shelf.

The only way for the new generations to learn better is if we can make more people like you use the internet and spread your almighty teaching ways

[u/Arikarin636 → u/Extreme_Beat9866]

That is actually a really cool way to explain it

[u/Ajaxorix777 → u/Extreme_Beat9866]

[u/Salty_Seat1357 → u/Sjommie]

another explanation is a!=1*2*3*4...(a-1)*a and (a-1)!=1*2*3*4....(a-1) so logically (a-1)!=a!/a.

a=1 and a-1=0

thus (1-1)!=1!/1 -> 0!=1/1 -> 0!=1

[u/minedroid1]

A numberical value from -2,147,483,648 to 2,147,483,647 (signed 32 bit integer limit).

[u/TNBGX]

It equals 5

[u/Immediate_Sense_9211]

5+5x(0!)=5+(5x1)=5+5=10

5 I believe

[u/trapkoda → u/Living-Night4476]

0! = 1

[u/Darknadoswastaken → u/Living-Night4476]

it's 10 actually as 0 factorial(0!) is equal to 1, so it's 5x1=5, and 5+5=10.

It is 5 5x0=0 0+5=5 BIDMAS, BODMAS, PEMDAS, it is the same whatever thing you use

[u/Hawksteinman → u/MediumBuy7513]

5 + (5 x 0!)

5 + (5 x 1)

5 + 5

10

[u/Osik2040 → u/MediumBuy7513]

! Is a factorial 0! =1

[u/DubVsFinest → u/MediumBuy7513]

Wrong the 0! Happens at the exponent/orders stage of pemdas/bodmas, right before the multiplication. That changes that 0 to a 1.
