Rebuilt from the ground up. Worked solutions are much clearer. Bars are drawn to the right lengths for the numbers in that question, braces line up with the parts they measure, and fractions sit properly over their denominators — so the model on screen looks like the one a teacher would draw on the board. Answers are checked more fairly. Dollars, fractions, mixed numbers, percentages, ratios and times are all accepted in the forms a Primary 6 child actually writes them, so a right answer is no longer marked wrong for its formatting. Every question type has been reviewed end to end — the wording, the numbers each one may print, and the working it shows. Ratios now come out in their simplest form, quantities stay sensible, and several solutions were rewritten to teach the model method rather than skip to the algebra. The two speed questions have been retired: speed is no longer in the PSLE syllabus. Speed questions already in your recent list still open and still show their solutions. Opening the app for the first time now takes you straight to a question instead of asking you to name a profile first. ProblemSum now requires iOS 18 or macOS 15.
