I really wonder how Gina get 16.8%. Should be genius or... |

nufan |
She did 12*1.4.. and she was wrong. |

This'll sound strange, but when I keyed the numbers into my TI BA II Plus Professional in % form, I got Gina's answer. Something goes wonky in the calculation when you enter the second % variable. |

me too! 16.8 |

In 5th grade they teach a little riddle that is (Please Excuse My Dear Aunt Sally) which stands for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. You have to do it in that order. The 16.8 number you are getting is by adding the risk free rate and the market risk premium before multiplying the beta. |

I remember reading in the calculator's manual that there is a setting to change the way the inputs are interpreted by the calculator. The default settings require the user to understand CRickert's rule (which in my opinion would go a long way to avoid future problems). However, these settings can be changed |

Another mnemonic is BODMAS(Brackets of Division, Multiplication, Addition and Subtraction) |

BEDMAS : Brackets. Exponents. Division. Multiplication. Addition. Subtraction. |
