How do you reset Casio fx-350ms?

Step 1: Turn on calculator by pressing "ON"
Step 2: Press "SHIFT" and then press "MODE" (Button to the left of "ON" button)
Step 3: Press "3"
Step 4: Press "="
Step 5: Press "AC" or "=" to complete the process

Hope this helps.
Figured this trick out myself

This is for fixing memory errors such as decimal places (in my case)
Ex. Normally the answer to 1+1 = 2 but in my case it was 1+1 = 2.0
