# Digital Font Puzzle. One easy the other may be not

In the Digital Font shown below, each letter is made up of line segments. For example letter A has 6, B has 7, C has 4 segments and so on.

Question 1 ( Easy)

Which english number, when spelled out (with capital letters) has the same total number of segments as the number itself?

( It is no fun going through each number. There is some logic here.)

Example : ONE has 6+5+5 = 16 segments

Question 2 ( Not so easy)

Which 2 numbers when added together give you a number same as the total number of segments in those 2 numbers? Ignore + sign segments. This must be other than the first number

Example : ONE + ONE = 2 But ONE + ONE = 32 segments not the right answer of course

What world is he thinking of?

• Just to clarify, are M and W intended to be 5 or 6 segments each? (They have 6 line segments but two appear to be joined into a single piece.) Mar 9, 2019 at 13:29
• They need to be 6 each

1:

THIRTY NINE: 3+5+2+6+3+3 (22) + 5+2+5+5 (17) = 39

2:

THIRTY EIGHT (22+21=43) + FORTY EIGHT (22+21=43) = 86

Some related curios:

THIRTY + NINE = THIRTY NINE
TEN (3+5+5=13) + FIVE (4+2+4+5=15) = FIFTEEN (4+2+4+3+5+5+5=28)
SEVEN (5+5+4+5+5=24) - FOUR (4+6+5+6=21) = 3

Method:

I first calculated each number ONE through NINE, TEN through NINETEEN, and then TWENTY, THIRTY, etc...

 one 6+5+5=16 (15)
two 3+6+6=15 (13)
three 3+5+6+5+5=24 (21)
four 4+6+5+6=21 (17)
five 4+2+4+5=15 (10)
six 5+2+4=11 (5)
seven 5+5+4+5+5=24 (17)
eight 5+2+6+5+3=21 (13)
nine 5+2+5+5=17 (8)
ten 3+5+5=13
eleven 5+3+5+4+5+5=27
twelve 3+6+5+3+4+5=26
thirteen 3+5+2+6+3+5+5+5=34
fourteen 4+6+5+6+2+5+5+5=38
fifteen 4+2+4+3+5+5+5=28
sixteen 5+2+4+3+5+5+5=29
seventeen 24+3+15=42
eighteen 21+15=36
nineteen 17+3+15=35
twenty 3+6+5+5+3+3=25
thirty 3+5+2+6+3+3=22
forty 4+6+6+3+3=22
fifty 4+2+4+3+3=16
sixty 5+2+4+3+3=17
seventy 5+5+4+5+5+3+3=30
eighty 5+2+6+5+3+3=24
ninety 5+2+5+5+3+3=23
hundred 5+5+5+6+6+5+6=38
For the single number, nothing less than twenty works so it must be a lexical composite, and a bit of reasoning tells which roughly where to be aiming.

For the sum, again you can get a rough idea. I hit upon thirty+forty=44. 44 is 26 short of 70, so to add the next numbers we need DF(a+b)=a+b+26. I calculated the excess for each single digit (the number in brackets), and a=b=8 gives my result.

And now, THIRTY=30-8, and NINE=9+8.

• Did you go through each number or could you find the logic behind? If so, what is it? Mar 10, 2019 at 23:36
• @AmitHagin; I've added an explanation
