Example Scenario & Underlying Math

Imagine a problem asking you to calculate the total cost of 5 items priced at $2.50 each. The on-screen calculator helps, but understanding the math is crucial:

Problem Type: Multiplication (finding total cost)

Variables Involved:

• Number of Items (N)
• Price Per Item (P)

Formula: Total Cost (C) = N × P

Calculation: C = 5 × $2.50 = $12.50

This involves multiplication, a fundamental operation directly supported by the TEAS on-screen calculator.

Practical Examples of TEAS Math Calculations

Here are a couple of realistic scenarios you might encounter on the TEAS Math section, illustrating how basic calculations are applied:

Example 1: Medication Dosage Conversion

A doctor prescribes 750 mg of a medication. The available concentration is 250 mg per 5 mL. How many mL should the patient receive?

• Concept: Ratio and Proportion or Unit Conversion
• Variables:
  • Prescribed Dose (DP): 750 mg
  • Available Concentration (AC): 250 mg / 5 mL
• Calculation Method 1 (Proportion):

  Set up the proportion: (250 mg / 5 mL) = (750 mg / X mL)

  Cross-multiply: 250 * X = 750 * 5

  250 * X = 3750

  Solve for X: X = 3750 / 250

  Result: X = 15 mL

• Calculation Method 2 (Unit Rate):

  Find the dosage per mL: (5 mL / 250 mg) = 0.02 mL/mg

  Multiply by the prescribed dose: 750 mg * 0.02 mL/mg

  Result: 15 mL

Calculator Use: The division (3750 / 250 or 5 / 250) and multiplication (750 * 5) steps would utilize the on-screen calculator.

Example 2: Calculating Percentage of a Whole

A nursing student needs to achieve at least 70% on the TEAS Math section to meet a program requirement. The Math section has 34 questions. What is the minimum number of questions the student must answer correctly?

• Concept: Percentage Calculation
• Variables:
  • Total Questions (T): 34
  • Required Percentage (P): 70% or 0.70
• Formula: Minimum Correct Questions (C) = T × P
• Calculation: C = 34 × 0.70
• Result: C = 23.8
• Interpretation: Since you can't answer a fraction of a question, the student must answer at least 24 questions correctly.

Calculator Use: The multiplication (34 × 0.70) step directly uses the on-screen calculator.

How to Use This TEAS Calculator Effectively
