TEAS NURSING EXAM: MATH:
ORDER OF OPERATIONS STEP 1: - CORRECT ANSWER-MUST BE IN CORRECT
ORDER: PEMDAS

P - PARENTHESIS

1. PERFORM OPERATIONS IN PARENTHESIS - WORK ON INNER-MOST SET
FIRST, THEN WORK OUTWARD.

4 + (3 x (5+2)) SIMPLIFY INNERMOST PARENTHESIS FIRST...

= 4 + (3 x 7) SIMPLIFY WITHIN PARENTHESI

=4+21 = 25

ORDER OF OPERATIONS STEP 2: - CORRECT ANSWER-PEMDAS

E - EXPONENTS

SIMPLIFY ANY EXPONENTS.

(3-1) 2(EXPONENT) + 6 - SIMPLIFY WITHIN PARENTHESIS

(2) 2 (EXPONENT) + 6 - SIMPLIFY EXPONENT

4+6 = 10

ORDER OF OPERATIONS STEP 3/4: - CORRECT ANSWER-PEMDAS

M- MULTIPLICATION D-DIVISION

COMPLETE MULTIPLICATION AND DIVISION FROM LEFT TO RIGHT:

2 x x 2 - FROM LEFT TO RIGHT

2 x 8 = 16

16/4 x 2 - FROM LEFT TO RIGHT

16/4 = 4 x2 = 8

ORDER OF OPERATIONS STEP 5/6: - CORRECT ANSWER-PEMDAS

,A- ADDITION S- SUBTRACTION

COMPLETE ADDITION AND SUBTRACTION FROM LEFT TO RIGHT

ORDER OF OPERATION EXAMPLE:

-2 (3-5+2) - CORRECT ANSWER-= -2(-2+2)

= -2(0)

=0

ORDER OF OPERATION EXAMPLE:

2 + 6 x 3 - CORRECT ANSWER-= 2+18

= 20

() x 5 - 6 + 2 x 7 -3 - CORRECT ANSWER-= 8 x 5 - 6 + 2 x 7 - 3

= 40 - 6 + 14 - 3

= 45

ONE & TWO STEP WORD PROBLEMS WITH WHOLE NUMBERS EX:

A DOCTOR MUST GIVE A PATIENT 100 MILLIGRAMS (MG) OF MEDS. THE MEDS
IS SUPPLIED IN 50 MG TABLETS. HOW MANY SHOULD THE PATIENT RECEIVE? -
CORRECT ANSWER-100/50 = 2 mg

ADDITION/SUBTRACTION OF FRACTIONS/MIXED NUMBERS WITH UNLINE
DENOMINATORS EXAMPLE:

1/4 + 1/6 = - CORRECT ANSWER-LDC: 12

= 5/12

ADDITION/SUBTRACTION OF FRACTIONS/MIXED NUMBERS WITH UNLINE
DENOMINATORS STEPS: - CORRECT ANSWER-TO ADD/SUBTRACT FRACTIONS
CONVERT ANY MIXED NUMBERS TO IMPROPER FRACTIONS FIRST.

THEN DETERMINE LCD (LEAST COMMON DENOMINATOR) - SMALLEST
COMMON MULTIPLE THAT BOTH DENOMINATORS DIVIDE INTO EVENLY.

, ONCE LCD FOUND, REWRITE EACH FRACTION AS EQUIVALENT FRACTIOON
WITH LCD.

ADD/SUBTRACT NUMERATORS - LEAVING DENOMINATORS SAME.

MAKE SURE SIMPLIFIED

ADDITION/SUBTRACTION OF FRACTIONS/MIXED NUMBERS WITH UNLINE
DENOMINATORS EXAMPLE:

2/3 + 5/12 = - CORRECT ANSWER-LDC: 12

1 1/12

ADDITION/SUBTRACTION OF FRACTIONS/MIXED NUMBERS WITH UNLINE
DENOMINATORS EXAMPLE:

3/8 + 5/6 = - CORRECT ANSWER-LCD: 24


1 5/24

ADDITION/SUBTRACTION OF FRACTIONS/MIXED NUMBERS WITH UNLINE
DENOMINATORS EXAMPLE:

3 - 5 1/3 = - CORRECT ANSWER-9/3 - 16/3 =

= 2 1/3

ADDITION/SUBTRACTION OF FRACTIONS/MIXED NUMBERS WITH UNLINE
DENOMINATORS EXAMPLE:

3/15 - 2/25 = - CORRECT ANSWER-3/15 = 1/5

2/25 - 5/25 =

3/25

MULTIPLICATION OF FRACTIONS/MIXED NUMBERS STEPS: - CORRECT
ANSWER-FIRST CONVERT ANY MIXED NUMBER INTO IMPROPER FRACTIONS.

SIMPLIFY/REDUCE FACTORS IN NUMERATOR W/ FACTORS IN DENOMINATOR.

MULTIPLY NUMERATORS TOGETHER & DENOMINATORS TOGETHER.

SIMPLIFY.
