# Add a letter to make this true

Add a letter to make this true. Please retain the = sign. (I consider solutions involving ≠, for example, to be trivial)

• equal by definition, as in, you are declaring that 148 is seven by definition which is an inherently true statement. (or a statement with no truth value depending on the propositional calculus model you are using) Apr 17, 2016 at 20:56

1 B 4 8 = 7

Because :

one before eight is seven (8-1 = 7)

• Nice one - you have it. Apr 17, 2016 at 20:55
• A rebus as a solution instead of the puzzle. I like it. Apr 18, 2016 at 13:39
• Ah I was thinking 1 from 8 = 7. I was trying to decide whether that should count, since you're exchanging a letter instead of actually adding one. Apr 18, 2016 at 20:10

148 = 7F

also

148 = 78
above is with digit, so replacing it with
148 = 7J

also

148 = 7D

because

${148}_{(10)}=7F_{(19)}$
${148}_{(10)}=78_{(20)}$
${148}_{(11)}=7J_{(22)}$
${148}_{(9)}=7D_{(16)}$

• The 2nd one doesn't work because 8 isn't a letter. Are radix systems just different bases? Apr 18, 2016 at 9:48

• @QuestionAsker Yes, they are indicated in subscript in the explanation. There are other examples too. With letters only ;) Apr 18, 2016 at 17:19

An italicized I over the top of the = turning it into ≠ or the not equals sign.

• For any questions in this format, like match stick/add a line problems, I would consider these solutions to be trivial. Please retain the = sign. Apr 17, 2016 at 20:43
• A lot of times the trivial solution is the one that the asker is looking for though, they are banking on the people overlooking the obvious (and trivial to one person is clever to another). I am not sure there is a good way to tag things to indicate what type of problem it is without giving away the solution... I think the only way is to make the problem more precise. if messing with = is not on the table, add it to the question. Apr 17, 2016 at 20:52
• Of course - no problem. Apr 17, 2016 at 20:54
• Maybe a no overylays statement when the word "add" is used since i have seen it used both ways in puzzles.. (add in between and add on top) for future puzzles of this form... Apr 17, 2016 at 21:00
• Actually, I think I can allow both, as there aren't any other solutions (at least I don't think), unless you try to cross the whole thing out or change the = sign. Apr 17, 2016 at 21:11

Add "m" to for ("4," get it?). 1 from 8 = 7

• You should use spoilers. Jun 11, 2016 at 13:37

• That's the first thing my friend said when I asked him, actually — "$148 = 7x$ where $x={148\over7}$" :) Apr 19, 2016 at 19:00
