Complex Number CIE - Maths 9709
I don’t take credit for these PPT slides because I have compiled very useful slides from different teachers together with 12 exam questions and my own worked solutions to help teachers and students in understanding complex numbers and teach at ease.
These exam questions should be useful for students to practice exam questions. It’s free and please do download and use them.
Also please comment if it is useless and your review motivates me to do more resources to help students understand and love Maths better.
