Worked examples

Example 1

The difference between two supplementary angles is 44°44°. Find the larger angle.
Show the worked solution
  • $\text{Let the larger angle be } x$
  • $x + (x - 44) = 180° \quad \scriptsize\textit{supplementary angles}$
  • $2x - 44 = 180°$
  • $2x = 224°$
  • $x = 112°$

Questions parents ask

Is it really free?

The free plan is permanent and does not ask for a card. It has daily limits on the AI feedback, and the paid plans lift them.

Which syllabus does this follow?

O-Level Mathematics (4052), for Singapore secondary students. Math Amigo covers Secondary 1 to 4, both O-Level Mathematics and Additional Mathematics.

Will it just show my child the answer?

No. On a wrong answer it looks at the working, points to the step that went wrong, and asks a question that helps the student find the correction. The full worked solution is available after a genuine attempt.
