Math but painful

i memorize it til the 125th number

wow (20 characters limits)

it’s nothing i planned to memorize 200 letters before i graduated from elementary but i failed :sob:

btw there’s a math problem in our school can anybody solve this?

10 * (-20) * 30 * (-40) * 50 * (-60) * 70 * (-80) * 90 * (-100) * 110 * (-120) = ?

4.790016e+20 i may have looked it up

I actually calculated it.

Solution

46,999,760,000,000,000,000

woah that’s unbelivable
thank you for your helps :slight_smile: :slight_smile:

Of course! BURN20CHARS

10 * (-20) * 30 * (-40) * 50 * (-60) * 70 * (-80) * 90 * (-100) * 110 * (-120)
12 numbers. Evens negative odds positive. Numbers in a sequence. (1 2 3 4 5 6 7 8 9 10 11 12):

  1. result is positive
  2. numbers can be simplified by removing zeroes and just adding e+[amount of zeroes] at the end
  3. if you pair the numbers into 6 pairs the numbers are all in the multiplication table
  4. simplified = 2 * 12 * 30 * 56 * 90 * 132 (I converted negatives to positives because there is an even amount of negatives which all cancel out each other)
  5. 2 * 12 is also in the multiplication table, so 24
  6. 24 * 30 * 56 * 90 * 132
  7. 24 * 30 is fairly simple, 24 * 10 * 3, 24 * 3 = 72 * 10 = 720
  8. 720 * 56 * 90 * 132
  9. remember it can be ordered in any order, so 720 * 90 = 72 * 9 * 10, 72 * 9 = 720-72 = 648 * 10 = 6480
  10. 6480 * 56 * 132
  11. multiplication process, 648 * 132 can’t be bothered to write it so I’ll just give result. 85536 * 10 (from the zero we removed in 6480)
  12. 855360 * 56 multiplication process again. 47900160
  13. 47900160 transfer the zero to the ‘e’, so 12 zeroes (12 numbers) + 1 extra zero
  14. 4790016e+13

Wrong

wrong
:]
(unless I made a mistake but that’s unlikely in my opinion)

4.790016e+20, I got the same as @TheCodingCrusader22

Sorry for replying so late but it’s really marvelous thank all of you :slight_smile:

its fine bro! 20 CHARS

although you can’t cancel out 0, as a-b=0

Is this possible to graph??

If that isn’t just a typo it’s probably referring to a point on the graph where y = 1 and -(x+2) = 1.
At least that’s how I read it.

very confused face
EH??

just had a math final (also im back ig?)

oh yeah, I didn’t notice the decimal point, sorry, that is correct xd although I’m not sure why the answer is e+20, from my calculations it’s e+19, but oh well

Some cooking with math terminology:

The golden ratio and pi are irrational, meaning that they cannot be represented by a ratio.

Yet both the golden ratio and pi ARE represented by a ratio, with pi being the ratio between the circumference and diameter and the golden ratio can be represented like this:

(1 + √5) / 2 ← ratio!

What makes it even more ironic is that phi (the golden ratio), IS LITERALLY CALLED A RATIO!
So where did we go wrong in math to mess up this badly?
Where there’s something I forgot to tell you, irrational numbers are actually just numbers that cannot be represented as a ratio between two integers. So, in reality, there really are no shenanigans here, just a funny way of twisting definitions. Still, I do think it is funny that the golden ratio is called a ratio when it’s irrational.
