 Question 205387: is it possible to use the digits 0-9 in an equation only using addition to add up to 100. Rules 1. you must use each number once and only once (no repeats) 2. you can group numbers together for example... 1 and 9 -> 19 (not adding or anything just using two of the numbers to form a 2 digit number) 3. I think that covers the rules if i seem to have left anything out let me know pattern i've noticed the only important thing is what the the tens places add up to ex1a. 13+24+5+6+7+8+9+0 = 72 (a multiple of nine) ex1b. 19+20+3+4+5+6+7+8 = 72 when the tens places add up to or equals "3" then the answer is always 72 ex2a. 12+34+5+6+7+8+9+0 = 81 ex2b. 45+1+2+3+6+7+8+9+0 = 81 when the tens places add up to ro equals "4" then the answer is always 81 hmmm... interesting the pattern continues each time the answer is always a multiple of 9 5=90 6=99 7=108 the person who gave me this problem insists very strongly that this is possible but i have found the opposite to be true your help would be much appreciated cause the only other way that i can think of is for my dad and i to write a program which will check every possible way the numbers can be rearranged etc. anyways, thx a bunch TJ Click here to see answer by jim_thompson5910(28504)
