Wait you did not realize this is super rare, jacob is also on the lable. That makes this cart extemely super duper rare.

oh, is that one of those misprints, kind of like coins when they strike it twice with the die?

Exactly!

Mine also has it on the box and overlay.

Which ROM variant is that?

Do the numbers enter left-to-right or right-to-left?

the number are bottom to top, no left or right

I am thinking of the number entry for the problems.

 

From the INTV Funhouse:

 

The allegedly older version of this ROM has you enter answers in "pencil and paper" order, while the later versions have you enter in "natural" order.

From The BSR (Intellivision Lives):

Initially, the solutions for math problems had to be entered ones column first. For example, when subtracting 5 from 24, the solution, 19, would have to be entered as 9, then 1. While this was designed to duplicate how people solve problems with pencil and paper, many customers complained; intuitively, they wanted to simply press in 1 then 9. A running change was ordered so that later copies of the cartridge use this intuitive method of entry, instead.

I have one of the ROM variants, I am looking for the other (I will have to check which, but my guess is that I need the pencil & paper ROM).

I was digging through some stuff a week or two ago and noticed I'd inserted a slip of paper into a box that tagged my I.I. copy of Math Fun as "backwards" entry. Don't make me dig it back out to verify this. Unfortunately, the original one we had back in the day no longer boots up. Not sure if it's actually dead or just a bad solder point somewhere...

 

...And, looking at the page, it seems there's a missing scan of the correction text from the PlayCable version of the manual. Someone needs to send a to-do list to that joker.
