Don't use a chart for Construct 7, really...

And we are talking about basic maths here, something you probably learnt before you started school, and if not certainly in your first year.

I do understand that this may be a lot more difficult for people with dyscalcula, but that's no different from people with dyslexia having to read onscreen instructions (which are a lot more prolific). It would be almost impossible for a developer to write a game which doesn't, at some point, affect someone with a disability.

Speaking of "learned" in school, in formal writing, coordinating conjunctions (for, and, nor, but, or, yet, so) are disapproved as sentence starting words. In addition, is "learnt" a word? Oh, and you forgot the comma after "and if not". Have some sympathy for those with math weaknesses Mr. Perfect English. When people attempt to make others feel that their skills are inadequate, it may just point out their own.
