1 + 2 = 3\n3 + 4 = 7\n7 + 6 = 13\n13+ 8 = 21\n21+ 10= 31\n31+ 12= 43

13+(-12)-(-15)=-16 because you subract 13 from 12 and get one.  Then you are left with 1-(-15).  When you have two negatives they become a positive.  Then the problem becomes 1+15=16\n\nHOPE THAT HELPS!

How is 15+12-6=92?\n\nYou must commited a blunder to get 92!\n\nIf the above equation has the answer 92, pls explain how. I would like to know out of interest

Sorry a12b13n5! - I think you are wrong on this one\n\nq +14 =8q + 8x7 (multplying out the brackets)\nq + 14 = 8q + 56 \nq - 8q = 56 - 14 (seperating the 'q's and numbers)\n\n-7q = 42\n\nthen devide by -7 to get\nq = -6\n\nto check\n-6 + 14 = 8 = 8(-6+1) = 8(1) = 8

i know how it's done. in the theorm, every number is one higher than stated (ex. 1=2, 2=3, 3=4, etc) since it's 2+2, it's actually 3+3. and if 3+3 =6, and 6=7, then the resulting equation is 2+2=7

7 will be after five\nand eight will be after six.\n\nReason: The upper numbers in 'numerals' contains straight lines, the lower one contains curves.\nWell...

it's only true if 8 is holding 12's spot.  then, when you're ready to solve, 12 comes back, thanks 8 for waiting in line, 8 goes off to do whatever the hell 8's do.. then the final answer is 6.

None of them because none of them = 18\n24\n13.8\n12\n36.6

Ah, but it is only 14 if you do math correctly.\n\n;-)

Well let's say the page to which she opened is n.  The seventh page after that is n+7, then n+14, then n+21, all the way up to n+140.  When you add all the n's together, you get 21n, and then there's the sequence of 20 multiples of 7.  So you have:\n21n + 7 + 14 + 21 + ... +140\nSimplified, this is 21n + 1470\nYou know the sum is 1995, so 21n + 1470 = 1995\nSubtract 1470 from both sides, then divide both sides by 21, and you get n = 25.

half of 12 is 6 plus 14_ 20

7\n\nUnless you are using base 6 or base 7.  In base 6, 2 plus 5 is 11; in base 7, it is 10.

13-5=8\n17-12=5\n15-8=7\nthe answer is seven.

1 + 7 + 7(6) + 42(5) + 210(4) + 840(3) + 2520(2) + 5040(1) = 13,700
