How every chapter teaches

Every wrong answer has a name.

The ASVAB rewards people who know what each question is really asking — and which wrong choice is waiting for them.

1 · The idea first

Explained like a teacher would, with a drawing when it needs one.

2 · A worked example

The whole line comes down, one change at a time — and the wrong attempt is shown too.

3 · The shortcuts

Checked and taken apart, never squeezed into a rule you have to trust.

4 · The traps, by name

The wrong answer the test offers, and why people fall for it.

From chapter 55 · The trapsThe wrong base

A ticket goes from $40 to $50. By what percent did the price rise?

Trap10 ÷ 50 = 20%

Rightthe change over the old price: 10 ÷ 40 = 25%
