August 29, 2020Amadasaid...Could you help me to solve this one:

1= 2

26 = 3

79 = 4

3 = 5

September 08, 2020Amadasaid...Could you help me to solve this one:

1= 2

26 = 3

79 = 4

3 = 5

? = 6

September 08, 2020Rajesh Kumarsaid...Can you please re-check the first term 1=2 or 1=3?

September 09, 2020Abdulsaid...Tell us what number 3 is

October 15, 2020Unknownsaid...I don't think that's it since 3=5 already, I did it my way where they substitute each other, but I can't find a reason why 79=4 so I can't prove myself right, right now I substituted everything and have this

1=2

1+4=5

?=6

3=5

4=6

that /=6 is what I can't proof, I'm not saying I'm right by any means, but I wish help to see if you can find a connection through my perspective of substitution and adding the connected numbers

October 26, 2020Unknownsaid...nvm I just realized I have small brain and I used all the numbers previously to add up to 6 so my whole theory is incorrect

October 26, 2020Unknownsaid...A=1, B=2, C=3 and so one till Z=26

So G+A = 7 + 1 = 8.
