SAT Subject Test Mathematics Level 2

|whatever|  <   p   means   −p  <   whatever    <   p

For example, |x − 5| < 14 becomes −14 < x − 5 < 14.

And here’s another general rule: To solve an inequality in the form |whatever |> p, where p > 0, just
put that “whatever” outside the range −p to p:

|whatever|  >p  means   whatever    <   −p  OR  whatever    >   p

For example, becomes OR .
