    Week One Math:
    The PSAT math test will cover math concepts you are already familiar with and simply need to review in order to score well.
    We will be memorizing the directions on the test, the formulas and completing practice drills to save time on the test and decrease your chances of making careless mistakes.
    For this first week we will memorize some formulas. Some of them you know quickly, for the others make a set of flash cards to practice with.
    Week One Formulas to know
    Write them down as you say them, if you don’t know them, look them up and put them on a flashcard, if you need help, just email me.

    Perimeter:     Square         Rectangle       Triangle                 Circumference of a circle
    Volume:         Cube            Rectangular containter
    Pythagorean Theorem
    Distance between two points in a plane
    Distance as a function of rate and time
    Mean                                Median

    Always be careful and read the question.
    •   Try: If x + 6 = 9, then 3x + 1 = ?
    Answer choices:
    (A) 3       (B) 9    (C) 10   (D) 34      (E) 46
    Let’s think it through. Choice A is to tempt you into a quick (wrong) decision. When you solve
    for x in the first equation (x + 6 = 9) you get 3, which is choice A.
    But that is not the question. You must go on to the second part of the question (3x + 1 = ?)
    Always be careful on two-part questions.
    •Choice C is the correct answer.
    1. Find the mean salary for four company employees who make $5/hr, $8/hr, $12/hr,
    and $15/hr.
    2. If x = 2 and y = -3, what is the value of 3x – 4y?
    A -6         B -2            C 12               D 14         E 18
    3. If x = -2, which of the following is greatest?
    A) -         B) 1 + x      C) 1 – x           D) -            E) x3
    4. Which of the following has the greatest value when x = 12?
    A) x         B) 2x         C) 2x ÷ 4         D) [2x ÷ 3] + 12         E) [2x ÷ 2] + (12 – 1)
    5. If 3x = 3x3 , what value(s) of x satisfy the equation?
    A) 0 only   B) 1 only   C) 0 or 1 only   D) -1 or 1 only        E) -1, 0, or 1
    Did you get them all? Did you make your flashcards?
