Since the comma trick doesn't work anymore and you're also required to type in both solutions for Algebra Antics it leaves us with very few options to speedrun this. Either memorize all equations and their answers or be lucky enough to stumble upon 7 calculators.
I would like to propose an alternative. Let us judge the runs for this specific category solely on the in-game timer, regardless of whether people bring up the pause menu for several minutes to calculate the solution on another tab. I for instance use the Steam overlay to quickly access a website that automatically does the math for you.
With the new update, there are a few changes that differentiate it from the previous version. Maybe we need a specific category for 1.1.0 runs as the current runs are more difficult to beat.
