ATI TEAS Mathematics Study Guide

Overview of TEAS Math Section

The ATI TEAS Math section tests basic math skills used in healthcare. You will see questions on numbers, algebra, measurements, and data interpretation.

Key Topics You Must Know

– Whole numbers, fractions, decimals, and percentages
– Ratios and proportions
– Algebra (solving for x)
– Conversions (metric & household)
– Word problems
– Data interpretation (charts, graphs, tables)

Fractions, Decimals, and Percentages

Be comfortable converting between fractions, decimals, and percentages.
Example:
3/4 = 0.75 = 75%

Ratios & Proportions

Set up proportions carefully.
Example:
2 tablets = 10 mg
How many mg in 1 tablet?
10 ÷ 2 = 5 mg

Algebra Basics

Solve for unknowns using basic equations.
Example:
x + 5 = 12 → x = 7

Measurement Conversions (VERY IMPORTANT)

Know these cold:
– 1 liter = 1000 mL
– 1 gram = 1000 mg
– 1 kilogram = 1000 grams
– 1 inch = 2.54 cm

Word Problem Strategy

1. Read carefully
2. Identify what is being asked
3. Write down given numbers
4. Choose the correct operation
5. Estimate to check your answer

Data Interpretation

Practice reading:
– Bar graphs
– Line graphs
– Tables
Look for trends, increases, decreases, and totals.

Calculator Tips

You will have a basic on-screen calculator.
– Do not rely on it for simple math
– Use estimation to catch errors

Test-Day Tips

– Memorize conversions
– Watch units closely
– Double-check decimal placement
– Skip hard questions and return later
