Casio fx300 Tips

This calculator is quite decent.

Memory Features

https://www.youtube.com/watch?v=_sCCbdLDXWY This one can create variables(lets call it the stack), and another we can add/subtract values to our previous memory pile(heap lets say).

Variables

Storing Variables

1. Type in a number
2. Shift+RCL → STO
3. Tap one of the alpha letters

Using Variables

There are 2 methods:

1. Use RCL, then tap one of the alpha letters
2. Alpha+alpha letter

Memory Heap

Adding/Removing to M

1. Have any value, whether it be from an equation, or simply a value typed in. at the end of the equation DONT press =, Instead, press M+ OR shift + M+ → M-
2. 
3. Clear right after, you don’t want to press = because that will repeat the memory addition

Viewing M

2 ways:

1. Use RCL, then tap M
2. Alpha + M

Limitations

• Cannot do logs of different bases
• Cannot graph
• no CAS
