Test Taking StrategyTest Taking Strategy• Multiple Choice problems; 4 answers each• No penalty for guessing; answer ALL questions

(25% chance of being right)• Every question has the same point value; do

easier questions firsto save harder ones until the end (guess if you have to)

• Make educated guesses; estimate; watch units of measure

• Keep track of the time; don’t get bogged down on one questiono 1 ½ to 2 minutes per question

Math PortionMath Portion• 34 questions / 51 minutes

o 20% of entire test for problems; 24% of entire test for time

• Schools set their own criteria for entrance scores• Calculators are NOT allowed • Topics covered in the Math Section

o Order of Operationso Fractions

• Multiplication & Division; Addition & Subtraction• Proper Fractions and Mixed Numbers 

o Percent, Ratios and Proportionso Estimationo Solving Basic Equations (one variable)o Absolute Valueo Measurements and converting between measuring systemso Interpreting data from graphs and diagramso Word Problems

Order of OperationsOrder of Operations

Decimal NumbersDecimal Numbers

Rounding NumbersRounding Numbers• Point to the column which represents the place

value you are rounding to (TARGET)• Look at ONE column immediately to the right

(NEIGHBOR) If NEIGHBOR is less than 5, leave TARGET alone If NEIGHBOR is 5 or more, increase TARGET by 1

• Zero all numbers to the right of TARGET

Decimal ArithmeticDecimal Arithmetic• Addition &

Subtractiono Line up the DECIMAL POINTSo Bring decimal point directly

down below in the answer

• Multiplicationo Line up RIGHT SIDE of numberso Ignore decimal points until endo Move decimal point from the

right side the same number of places as both original numbers have, combined

• Divisiono MUST divide by whole

number!!o Move decimal point inside the

same number of places as you move the outside point

o Pop the decimal point up into the answer immediately

Roman to ArabicRoman to ArabicM = 1000 D = 500 C = 100 L = 50 X = 10 V = 5 I = 1

•Add values left to right•If I, X, or C appears to the left of a larger value, subtract that value from the larger one MMCDLXXIII =

1000+1000+400+50+20+3 = 2,473

CXLVII =

100+40+7 = 147

Arabic to RomanArabic to RomanM = 1000 D = 500 C = 100 L = 50 X = 10 V = 5 I = 1•Convert each place value into Roman #’s•I, X, C can be used up to 3 times in a row after larger values•I, X, C at the left of larger value is subtracted•V, L, D never used more than once

756 =

700 = DCC 50 = L 6 = VI 756 = DCCLVI

3,409 =

3000 = MMM 400 = CD 9 = IX 3,409 = MMMCDIX

FractionsFractionsMultiplication & Division Addition & Subtraction• Don’t care about

denominators being the same

• Multiply straight across both top & bottom

• Multiplying is the ONLY time you can cancel

• Dividing: Keep, Change, Flip

• MUST have same denominator!!!

• Add or Subtract top only and KEEP denominator the same

• Build up fractions to have same denominator by multiplying by 1(same number top & bottom)
