HP Prime giving a number when trying to simplify an equation.
12062019 04:43 PM
The equation I put into the CAS simplify is 12*(3*S*4*T)18*(3*S+4*T)*(3*S4*T)+12*(3*S+4*T)9*(3*S+4*T)^2. The answer I keep getting is 2981.16 and not a simplified equation. Any reason why Prime is setting variables S and T to be a number?

Prime uses the uppercase letters A through Z as realnumber variables which always have a value. More information about these variables, and all other variable types and usage syntax, can be found in your Prime's User Guide, Chapter 24, "Variables".
Hint: If you want to use CAS on symbolic variables, use lowercase letters, e.g. s and t. Until they are given values, they remain purely symbolic, unlike S and T which always contain a value.
