Worked examples

Equations and inequalities with absolute value

One sheet for each type of problem, with several worked examples of increasing difficulty: first the computation, then the explanation in words. Each sheet starts with links to the theory it uses.

• 1Equations of the form |A| = k and |A| = |B|
• 2Equations of the form |A| = B
• 3Inequalities of the form |A| < k and |A| ≤ k
• 4Inequalities of the form |A| > k and with an expression on the right-hand side
• 5Equations and inequalities with two absolute values
