uhm... maybe I made a mistake:*Originally posted by phgao***1. Adab + Cbb + Caa = Abda**

2. Abab - Cdd = Bac

3. Abab - Ccba = Ccdc

4. Efg + Gf + Gef = Bdfg

5. Abcb - Deac = Eadd

Note that A = a, B = b et cetera.

1. 1021A+12B+200C+100D = 1001A+100B+10D

20A+200C+90D=88B

2. 1010A +101B - 100C - 11D = 100B + 10A + C

1000A + B = 101C + 11D

3. 1010A + 101B – 1100C – 10B - A = 1101C + 10D

1009A + 91B = 2201C + 10D

4. 110E + 12F + 111G = 100B + 100D + 10F + G

110E + 2F + 110G = 100B + 100D

5. 1000A + 101B + 10C - 1000D – 100E – 10A - C = 1000E + 100A + 11D

890A + 101B + 9C = 1100E + 1011D

10A + 100C + 45D = 44B

1000A + B = 101C + 11D

1009A + 91B = 2201C + 10D

55E + F + 55G = 50B + 50D

890A + 101B + 9C = 1100E + 1011D

the only possible numbers in the first one are:

A = 3

B = 5

C = 1

D = 2

then you get:

30+100+90=220

220=220 (i'm a genius )

but if you look at the second:

3000 + 5 = 101 + 22

3005 = 123 uhm... I don't think that's correct...

so, are you really sure you didn't wrote a letter wrong? - 21 Jul '05 12:24 / 2 edits

Oh sorry for the second one it should be Abab - ccd = bac*Originally posted by Florrat***uhm... maybe I made a mistake:**

1. 1021A+12B+200C+100D = 1001A+100B+10D

1000A + B = 101C + 11D

3. 1010A + 101B – 1100C – 10B - A = 1101C + 10D

1009A + 91B = 2201C + 1 ...[text shortened]... ct...

so, are you really sure you didn't wrote a letter wrong?

But the 1st one is correct. Each one has a separate solution. So the A for Q1 doesnt have to be the same a in Q2 etc. - 21 Jul '05 16:06 / 1 edit

these are the solutions (2 and 4 have multiple answers...):*Originally posted by phgao***Oh sorry for the second one it should be Abab - ccd = bac**

1. 10A + 100C + 45D = 44B A = 3, B = 5, C = 1, D = 2

2. 1000A + B = 111C + D A = 1, B = 2~7 = D-1, C = 9, D = 3~8 = B+1 (6 possible solutions)

3. 1009A + 91B = 2201C + 10D A = 2, B = 3, C = 1, D = 9

4. 55E + F + 55G = 50B + 50D B = (1~)2, D = 8(~9), E = (1~)3, F = 5, G = 6(~8) (E&G can be rotated, B&D can be rotated,

so 3 * 4=12 possible solutions)

5. 890A + 101B + 9C = 1100E + 1011D A = 3, B = 5, C = 4, D = 1, E = 2

Sorry, I hated this primary school stuff, how you wrote all these stupid things down:*Originally posted by phgao***Some more for you to toss around.**

-*---GT

_________

---VW

---TVW

what you have to do?

-----,VW * (- * ---GT) = -----IW + ---VW = ---TVW

or do you lose information now?

Is this even possible? (if you multiply the lowest numbers with both at least 5 digits, you should get at least 9 digits) - 23 Jul '05 09:38 / 1 edit

Ok... since my typing isnt up to scratch, ill try to explain...*Originally posted by Florrat***Sorry, I hated this primary school stuff, how you wrote all these stupid things down:**

the "........" and ",,,,,,"s dont mean anything. This is a multiplication, only look at the letters. I use "........"s so they line up. That is how the sum multiplies out when completed. _______ is just a line separating the top middle and bottom of the multiplication. - 23 Jul '05 14:10 / 2 edits

musn't that 'IW' have 3 digits, because I solved it so far:*Originally posted by phgao***Some more for you to toss around.**

T = 6 because W*T=W or W+10, W+20, W+30, W+40 so T = 1 or 6. T can’t be 1 because T*V= I

V = 5 because IW+VW0=6VW and V can’t be 6 because T=6

G must be 1, because 10*G*5W=5W0 so G*5W=5W so G=1

I+W=(65-50=)15. T=6 so they must be 7 or 8

W = 7 or 8
