Last week, I was sharing with my O-Level E-Maths students on the calculation of mean and standard deviation by using the calculator. Almost everyone is using the Casio 95 SG Plus or similar model.
There was a student who used Sharp model which I wasn't so familiar with initially. But we figured out the usage for the calculation anyway.
I decided to check if the Sharp model calculator is approved for O-Level.
Here's the list of approved calculators for O-Level Maths, check and ensure your calculator is allowable. Otherwise, buy a new one now.
