299,999 is divisible by 7 and 17.
So simple math problems are blowing people’s minds now?
Always has been.
Just wait for the annual “PEDMAS vs PEMDAS”
discussionflame-war on any major social media platform.Why? Not sure what the debate is, if you divide/multiply first?
It can matter if you don’t have enough significant figures, so I tend to do division last to preserve as much precision as I can. In theory it shouldn’t matter, but it can matter in practice.
So the debate is whether it could or could not matter?
No, the debate is stupid.
I’m just saying there is a situation where it could matter, not that the debate is valid.
Ah, I’m still trying to figure out what the debate is. Sorry mate, but thanks for trying to respond, I appreciate you having tried. I’m just missing something.
I am more impressed that people know about divisibility. What’s next, random people knowing about ideals?
three is the first number that starts to cause problems.
Three is my favorite number, you take that back.
If it bothers your OCD, think of it more as (7x3)+(10x3)=17x3=51
Dude/ Dudette that’s worse. 7x3=21, 10x3=30, 21+30=
49251That does less insane to the membrane
I see them as the same except that your way illustrates what his parentheses are doing.
The way I see it the parentheses are good, it the 17x3 that hurts my brain.
It’s already broken down, then gets more complicated by the 17x3. In my mind I now need to separate 17 into 10 and 7 then multiply them each by 3 and add them together, which is where we started in the first place.
Brains are different, that’s how mine goes though.
I understood that to be a reference to the original screenshot. Thus the two equal signs. It was a way to walk you through how the breakdown ties back in.
¯\_(ツ)_/¯Not disagreeing, and I upvoted you for a different perspective. I did not see it that way, though I do now.
Like I said, brains are different.
Nah, 45 + 6
153 + 23
Or the way I do it:
- 3 * 20 = 60
- 60 - 51 = 9
- 20 - (9 / 3) = 17
So the factors are 17 and 3. I know 3 is a factor because 5+1=6, which is divisible by 3, so I just use a convenient multiple of 3 that’s pretty close to the actual number to get the divisor.
I have young kids and they keep asking me to do crazy math problems while driving, so that’s generally the trick I use.
This is how I have always calculated in my head. It used to drive my mom and my teachers crazy when they asked me to verbalize my calculations. It was like I was hurting them somehow. I never understood why.
3 is the real culprit
Good news, everyone. 314159 is not evenly divisible by 17, just as you’d expect.
A bit random no?
So when I turn 51 I can get into a relationship with three 17 year olds and all together they will be a perfect match for me… 🤔
Math is awesome.
Punctuation.
And capitalization. Pretty much any device can do both for you, don’t be lazy…
I’ve been aware of this since I was about 8. Not sure what Chloe is so upset about.
Maybe she was 2 cents short of figuring out the answer she was looking for?
