I saw my friend using Galaxy note 2 to write down mathematical formulas in lecturing math class. She said "It's all built it in the device it self, you just write down with s-pen or even with fingers it will automatically transcript to text it self." She also told me that Galaxyt Note 3 is new-released. So I went to Samsung store. Galaxy note 3 were awesome!! I was palnning on buying 5s when it's available, not anymore! Now to the point As I am abouth to buy it I tried the S-note....Mathemetic formulas weren't there. I ask the staff in the store they couldn't help me find it. (I'm in Thailand, most staff have no idea about the products they are selling.) So I'm here to ask. are there still mathmetical formulas on G.Note 3. If so how do I find it? Is there any VDO tutorial on it. I'm new to android Ps. Apology for my bad english.
