2, 3, 9로 나눌 수 있음

Here's my previous blog entry in Korean. Would be nice to know from a native speaker if Google Translate did a good job:
NumberWiz 애플 리케이션에서 그 같은 산술 문제를 해결하면, 그것은 결과의 정제를 확인 좋아요. 마지막 숫자도있다 : 그것은 두 번째로 나눌 수 있는지 알아 하찮은거야.
자리를 추가하고 표시되는 결과가 세번째로 나눌 경우 : 그것은 숫자가 3 수없는 경우보세요 "도 쉽게 결과가 너무 큰 경우, 그냥 결과의 자리를 추가하고 볼 수있는 새로운 결과가 세번째로 나눌 경우 예 1,375,896. 1 3 7 5 8 9 6= 39번째 도 계속해서 확인을 큰 : 3 +9 = 12. 아직까지도 계속해서 확인을큰 : 1 +2 = 3. 셋째로 나눌 계산기 1,375,896 = 458.632 엑스 3 말합니다.
당신이 일상 생활에서 아는 소수를 위해보십시오. 27 : 2 7 = 9. 셋째로 나눌99 : 9 +9 = 열여덟번째 1 8 = 9. 셋째로 나눌 34 : 3 +4 = 7. 아니 세번째로 나눌 13 : 1 3 = 4. 아니 세번째로 나눌

Divisibility by 2, 3 and 9

When solving arithmetic problems like those in the NumberWiz app, it's good to check the divisibility of the result. It's trivial to find out if a number is divisible by 2: the last digit is even. 
It's also easy to find out if a number is divisible by 3: add the digits and see if the result is divisible by 3. If the result is too big, just add the digits of the result and see if the new result is divisible by 3. Example 1,375,896. 1+3+7+5+8+9+6 = 39. Too big, ok continue: 3+9=12. Still too big, ok continue: 1+2=3. Divisible by 3. The calculator says 1,375,896 = 458,632 x 3.
Try it for smaller numbers that you know from everyday life. 27: 2+7=9. Divisible by 3. 99: 9+9=18. 1+8=9. Divisible by 3. 34: 3+4=7. Not divisible by 3. 13: 1+3=4. Not divisible by 3.
Same rule applies to divisibility by 9. Example: 470,761,587. 4+7+0+7+6+1+5+8+7=45. Too big, ok continue: 4+5=9. Divisible by 9. The calculator says 470,761,587 = 52,306,843 x 9.
Really simple and useful rules of arithmetic. I'll go through other rules later. I'm particularly fond of the rules for 3 and 9, because they're so simple. What's more: every second number is divisible by 2 and every 3rd number is divisible by 3. This makes the rules even more useful!

Excitement over the app release

Probably due to the excitement of the new app release, I forgot to show the game icon on the blog. Corrected that now by adding it to the previous post. Please have a look at the icon on the January 27 post.

The New App has Arrived

Proctele's new app has arrived. It is written for iPhone, iPod touch and the iPad.
It has different names in different languages:


English:  Elephant Super Memory Challenge: Recall This!

French: Challenge Elephant Super Memory: Rappel Ce!

German: Elefanten Gedächtnis Herausforderung
Swedish: Elefantminne: Memorera detta!
Dutch: Olifant geheugen: Dit memoriseren!

It's a game that presents a string of objects, either alphabetical or numerical or both, or colors, or smileys. After a while (the player chooses how long a while) they become hidden. Now it's up to the player to repeat the sequence with a suitable keyboard. You decide how long the string is and how long time you have to input the sequence.

Answer to the 395 Q

The Question was: How to add, subtract, multiply and divide 5, 8, 9, 10, 50, 100 to get 395 ?

Answer 395 = 50 x 8 - 5

I have some great news coming up later today.

Getting to 395

How do you add, subtract, multiply and divide the numbers 5, 8, 9, 10, 50, 100 to get 395 ?

The above question is typical of NumberWiz, the game of arithmetics for iPhone/iPod touch. It is also adapted for the iPad, where it looks even better. Search for NumberWiz in the App Store.

Getting to 233

The question was: How do you add, subtract, multiply and divide 2, 3, 4, 8, 50, 75 to get 233 ?

Answer: 233 = (3 x 75) + 8 =  225 + 8

Chuck Norris visit

This week-end Proctele had a celebrity visit. We had the great honor of receiving Chuck Norris as our guest. 

We went for some sight-seeing and hiked in the woods not far from our office. And then, deep in the woods, something happened that I had been hoping for: we met a wild animal. Doesn't normally happen this time of year, but we met a brown-bear. And he was ANGRY, very angry, because somebody woke him up from hibernation. Chuck got angrier than the bear though: he threw a couple of punches and the bear sailed head first right into a lake (at walking distance). He didn't bother us again.

Back home, my wife cooked us a double T-bone each and then Chuck had to fly off. He left behind loads of advice for our iPhone app development team and entered his jet saying "Keep up the good work so we'll see a steady flow of apps coming from your great company!"

Great visit by a Great man!

And here's a NumberWiz sum, a simple one:

290 solution x 2

The question was: How do you add, subtract, multiply and divide the numbers 1, 2, 7, 8, 25, 100 to get 290 ?


Answer: 290 = (25 + 1) x 7 + 100 + 8


Alternative: 290 = 8 x 25 - (7 + 2 + 1) + 100 = 200 - 10 + 100

The 810 solution

The question was: How do you add, subtract, multiply and divide the numbers 2, 4, 6, 8, 25, 50 to get 810 ?


Answer: 810 = (50 x 8 x 2) + (6 + 4) = 800 + 10

NumberWish: 810

You only need 3 of the numbers

Question was: How do you add, subtract, multiply and divide the numbers 2, 8, 9, 10, 25, 75 to get 130 ?

Answer: 

130 = (75 - 10) x 2

Alternative answer:

130 = 75 + 25 + (9 - 8 + 2) x 10 = 100 + (3 x 10)

Sales pitch for the next app

Today I've written a sales pitch for the next app I mentioned in the previous post. It's the pitch that appears in the App Store and I've written it in 5 languages: English, Swedish, Dutch, German and French. 
Thank you Google for Google Translate and I thank my wife for correcting Google's French translation. In fact I even use Google Translate to translate from the English original into Swedish, my native language. That means I only have to correct Google's translation, and that saves me time.
The app-icon is ready. Testing has revealed the last few bugs ;-) There were only a few memory leaks. I expected more of them. Now I have to play with the app for a while before release. Lovely jovely!

New game coming soon from Proctele!

I thought I'd let readers of the blog get the news first: A new app will be released in a couple of weeks, hopefully within 3 weeks. 


The icon is being designed just now. Testing is ongoing. 
I will be coming back to this subject in the coming weeks.

Only Chuck Norris can !

How do you add, subtract, multiply and divide the numbers 1, 1, 2, 2, 3, 3 to get 65 ?


Well, here it is:
(3 + 1) x (3 + 1) x 2 x 2 + 1 = 65.


The last 1 is Chuck Norris's privilege, because nobody says NO to Chuck Norris.

Chuck Norris Example NumberWiz Fact

Chuck Norris handed me this example: 
How do you add, subtract, multiply and divide the numbers 1, 1, 2, 2, 3, 3 to get 65 ?


(I'll have to consult NumberWiz to solve this one)

NumberWiz, the brainy iPhone app

How do you add, subtract, multiply and divide the numbers  2, 3, 3, 7, 8, 25  to get 838 ?

NumberWiz, the brainy iPhone app, found this answer:

838 = ((8 + 3) x 25 + 2) x 3 + 7 = 277 x 3 + 7

That one was difficult.

Chuck Norris Facts (again)

Chuck Norris has a special version of NumberWiz, which allows him to select the numbers. I'm sorry folks, but he demanded it. I do not say no to Chuck Norris.


Chuck Norris loves NumberWiz. I love Chuck Norris. It would be unwise not to.


Chuck Norris hates to play NumberWiz on Nintendo Wii. That's the reason it's not available on the Wii.

NumberWiz example: 536 = 67 x 8

Question was: How do you add, subtract, multiply and divide the numbers 1, 2, 5, 7, 8, 25 to get 536 ?


536 = (7 x (5 + 1) + 25) x 8 = (42 + 25) x 8 = 67 x 8

Chuck Norris got this right in much less than .001 seconds

The 867 one

Question was: How do you add, subtract, multiply and divide the numbers 6, 10, 25, 50, 75, 100 to get 867 ?



An answer: 867 = (100 - 6) x 10 - (75 - 50 / 25) = (94 x 10) - 73


Would be interesting to know if anybody found another solution.
