It works as documented in the Calc manual, section 5.15 Formulas:
C-h i m calc RET 5 m formulas RET
Calc gives '/' lower precedence than '*' by default.
To make Calc follow C-like rules, you can set it with the command
calc-c-language. You can read its documentation with:
C-h i m calc RET i calc-c-language
