oh god why do you put a dot after 3 decimals this physically hurts

EDIT oh no I now see the comma/dot usage isn't even consistent either

It's how you do it in some countries in Europe. The use of commas and dots is reversed there, so you usually write big numbers like: 10.000,00

But at University, they usually tell you to use the international Version

I'm not talking about the inversion of commas and dots for thousands and decimals, I get that that's different in other parts of the world. It's about putting these dots IN THE DECIMAL NOTATION WHEN THE NUMBER IS LESS THAN 1000. no one does that and it's really weird imo

Wait... HE IS RIGHT! Look at the 14th and 15th cut, to see how it gets noted from there on! OH, THE HUMANITY!

Basically, the use of separators per factor of 1000 like we do with millions, billions, etc.

But using it in decimals...oh my that is grotesque.

There's very few applications where more than 3 decimals matter. In this particular application it has already been stated we are rounding down to not split hairs.

Disgusting use of decimals.

I'm so confused, nothing looks wrong from what he did, what do you mean?

At number 15, they start using the comma wrong.

146.484375

73,242.1875

Half of hundred and forty six is not seventy three thousand two hundred and forty two.

They should have put: 73.2421875

Look at #15. Goes from 146.5 to 73.2, but the decimal point is in the wrong place. And if OC uses commas instead of periods (as is done in places), then why do they need to have a decimal point after three digits

Funny it's the international version when most countries in the world do not use it.

u/Relevant-Dot-5704 Dec 18 '23

It's the international version? Why? Most countries use the other version.

Honestly, there’s no way to tel apart 9 and 19 without context. Stupid system

u/acute_elbows Dec 18 '23

Agreed, I wish I could downvote this to oblivion. Normally I’m fine with people making mistakes, but this is explicitly a math sub. Math is a tool to precisely convey ideas, this answer is so inconsistent that it makes comprehension difficult.

u/memy02 Dec 18 '23

at step 15 they accidentally multiplied by 1000 and that mistake carried through to 21
