Oh yeah. Percents and ratios and estimating. Man, I think I’ve used percents and ratios and estimating my whole life. How many parts of this to that? Even cooking is easier with ratios rather than measurements.
And… money math. Money math is… weird and not quite like school math. Things don’t balance out in money math in the same way yet they also still have to. It’s weird. They say it’s the same but it’s not.
