Key tactics

Encountering math questions on the LSAT can be an unwelcome surprise for many, and at first blush many of these questions seem incomprehensible. Fortunately, the list of math concepts commonly tested is pretty short, and with a bit of dedicated practice (see the linked lessons) these questions will become reliably solvable.
As with many common LSAT tricks, mastering the Math tag is mostly about recognizing that various concepts are distinct from one another. For example...
...just because there are a large number of flat earthers in the world (call it 10,000?), that does not mean a large percentage of people are flat earthers.
...just because the average NBA player is 6'7" tall (true fact, btw), that does not mean any given NBA player is 6'7" tall (Steph Curry, for example, is 6'2").

Answer choice tips

Example answer choices that point to math flaws:
assumes that an increase in the proportion of knee injuries rules out a decrease in the number of knee injuries.
confuses the percentage of the budget spent on a program with the overall amount spent on that program.
overlooks the possibility that a generalization true of the entire group of volunteers was not true of each of the five smaller groups.
