Re: Mental arithmetic making you look bad?There's a website named after that, so I'm not sure that would be a good idea... #28 20061217 19:21:26
Re: Mental arithmetic making you look bad?ARe they held in Mathens Greece? A logarithm is just a misspelled algorithm. #29 20061217 19:22:09
Re: Mental arithmetic making you look bad?No, in Mathland. Next to Cleveland. #30 20061217 19:29:09
Re: Mental arithmetic making you look bad?Lol! A logarithm is just a misspelled algorithm. #31 20061219 14:38:40
Re: Mental arithmetic making you look bad?OK. I have a version of Reaction Math for you to try out. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #32 20061219 15:38:59
Re: Mental arithmetic making you look bad?The game is fun! X'(yXβ)=0 #33 20061219 17:10:10
Re: Mental arithmetic making you look bad?
Well, 0.735 seconds for add single and 0.969 for multiply 10x10 (with all correct!). I'm sure someone will easily beat them but I thought I better make a start ... #34 20061219 17:16:55
Re: Mental arithmetic making you look bad?Great stuff, mathsisfun! Its perfect! Last edited by mikau (20061219 17:32:31) A logarithm is just a misspelled algorithm. #35 20061219 17:42:15#36 20061219 22:18:02
Re: Mental arithmetic making you look bad?Hmmm. I'm having problems with it. Even if I type the correct answer it still marks it wrong (you can see by the log it keeps) #37 20061219 23:31:01

Or "Sum Sum" Last edited by LQ (20061219 23:34:04) I see clearly now, the universe have the black dots, Thus I am on my way of inventing this remedy... #38 20061220 00:14:46
Re: Mental arithmetic making you look bad?I'm not sure why it's not working for Toast, because it works very well for me. Why did the vector cross the road? It wanted to be normal. #39 20061220 00:29:04
Re: Mental arithmetic making you look bad?for 12x12 i got average of 1.4s The Beginning Of All Things To End. The End Of All Things To Come. #40 20061220 00:50:23
Re: Mental arithmetic making you look bad?Thanks mathsyperson, it's working ok now. Last edited by Toast (20061220 00:53:01) #41 20061220 04:26:44
Re: Mental arithmetic making you look bad?
holy smokes... thats pretty good. I average like 10 seconds for the double subtraciton. Last edited by mikau (20061220 04:27:07) A logarithm is just a misspelled algorithm. #42 20061220 06:40:44
Re: Mental arithmetic making you look bad?
It said 7x8, and I put 56. It said I was wrong for some reason. #43 20061220 06:44:49
Re: Mental arithmetic making you look bad?Something a little wrong with this game...keeps saying I'm wrong. Last edited by Devanté (20061220 06:58:00) #44 20061220 07:25:43
Re: Mental arithmetic making you look bad?Got 1.635 for double subtraction. Last edited by Devanté (20061220 07:33:45) #45 20061220 08:23:01
Re: Mental arithmetic making you look bad?You guys are so awesome! This is great. Add this to games if you haven't allready... I see clearly now, the universe have the black dots, Thus I am on my way of inventing this remedy... #46 20061220 10:17:43
Re: Mental arithmetic making you look bad?Very nice software indeed!! Much enjoying. igloo myrtilles fourmis #47 20061220 11:03:24
Re: Mental arithmetic making you look bad?Wow, glad you like it, and thanks for the very nice compliments! (blush) "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #48 20061220 11:18:07
Re: Mental arithmetic making you look bad?I find that I just know all the multiples up to 10x10. I never actually memorised them properly, but as you use them so often while doing other things you tend to just learn them anyway. Why did the vector cross the road? It wanted to be normal. #49 20061220 18:08:44
Re: Mental arithmetic making you look bad?At my school we learnt the multiplication to 12*12 in grade 3. Hmmm, there was this guy who could recite the 6 times tables in 7 seconds o_O, yeah, I'm glad we had those multiplication races. #50 20061220 18:24:55
Re: Mental arithmetic making you look bad?People often give me stupid things to work out in my head and they'd give me 515 seconds to work it out. If it was simple, like 537x7, I'd easily just do:
