By the way, the number closest to 13 is not 13, but 14 or 12 (whole numbers). He prolly meant closest number with 0 at the end.
One more trick:
First subtract 2 from the number.
Then find the square of the number
then add 4 to the result.
thanks for the trick
By YqYx 1191279729 Reply Spam [+0] Moderate Up Moderate Down RemoveI did this before. I mean.. I guess I'm not the only one who found out about this. I even thought that this isn't worthy of my pride so I didn't actually tell it to anybody except my family of course. Great minds think alike.
PS
Chain letters dont work. Trust ME!

By taekkwon 1190137852 Reply Spam [+0] Moderate Up Moderate Down Removeyou are a genius.
great stuff.
Doesn't this trick only work with numbers close to base 10? I tried with 37, and it didn't work. 37 is close to 40, so 3. 37 3 = 40. 40 * 40 = 16000. 3@ = 16009.
By RickyTheFish 1189140711 Reply Spam [+0] Moderate Up Moderate Down Removeit should be like this
=(37-3)*(37 3) (3*3)
=1360 (3*3)
= 1369
it works.
something happened with my original post, plus I miscalculated. But it's still wrong. 37 is close to 40 so 3. 37 3 = 40. 40 * 40 = 1600. 1600 3squared = 1609. 37 squared = 1369. Therefore this is wrong, except for numbers close to base 10.
By RickyTheFish 1189140900 Reply Spam [+0] Moderate Up Moderate Down RemoveApologies for the multiple postings, but apparently Metacafe does not like the plus sign, which is why it doesn't display in my posts. That is why they look strange.
By RickyTheFish 1189140949 Reply Spam [+0] Moderate Up Moderate Down Removeit should be like this
=(37-3)*(37 3) plus(3*3)
=1360 plus (3*3)
= 1369
it works.
it should be like this
=(37-3)*(37 plus 3) plus (3*3)
=1360plus(3*3)
= 1369
it works.
Yeah, I was doing it backwards. You reverse the sign for the number you subtracted or added to the original. So 37 is close to 40, which is plus 3. 37 minus 3 is 34. 40 times 34 equals 1360. Plus 3 squared is 1369. Sorry, you're right.
