TEAS 7 Math Section: High-Yield Topics, Dosage Math, and How to Pass
The TEAS 7 Math section is 38 questions in 57 minutes across Numbers & Algebra and Measurement & Data. Here is exactly what ATI tests, the high-yield topics that win the most points, the metric and dosage conversions to drill, and a two-week study plan.

The TEAS 7 Math section gives you 38 questions in 57 minutes — about 90 seconds each — across just two areas: Numbers & Algebra and Measurement & Data. It is the section where confident students freeze, usually because they have not touched algebra since high school, not because the math is hard. The content is middle-school to early-high-school level, dressed up in nursing scenarios. The good news: it is narrow and predictable. A handful of topics — ratios, proportions, metric conversions, and dosage calculations — show up far more than anything else, so if you drill the high-yield few instead of re-reading a 400-page prep book, you can pass this section on your first attempt. Here is exactly what is tested, which topics earn the most points, and a two-week plan to get there.
What's actually on the TEAS 7 Math section
Of the 38 questions, 34 are scored and 4 are unscored pretest items that ATI uses to trial future questions. You will not know which are which, so treat every question as if it counts. You also get a basic four-function calculator built into the screen. According to ATI's official TEAS exam details, the 34 scored questions split across two content areas like this:
Content area | Scored questions | Share of section | What it covers |
|---|---|---|---|
Numbers & Algebra | 18 | ~53% | Fractions, decimals, percentages, ratios and proportions, basic algebra, and word problems |
Measurement & Data | 16 | ~47% | Metric and household conversions, geometry basics, reading graphs and charts, and mean/median/mode |
The split is close to even, so unlike the Science section there is no single area to over-invest in. The smarter lever is topic, not area. A few topics — ratios and proportions, metric conversions, and percentages — turn up again and again, often woven into the dosage word problems that dominate both areas. Drill those and you have covered most of the test.

The high-yield topics that make up most of the section
Stop trying to master every formula in the prep book. Most of the points live in a short list of topics, and most of those topics are really the same skill — setting up a proportion and cancelling units — wearing different clothes. Focus here first:
Ratios and proportions — the single most important topic, and the backbone of dosage math. Use one setup every time: what you have / 1 unit = what you need / x units, then cross-multiply.
Unit conversions — metric and household. They appear on their own and hidden inside dosage problems, so their real weight is higher than the question count suggests.
Percentages — finding a percent of a number, finding what percent one number is of another, and percent increase/decrease.
Fractions and decimals — converting cleanly between fractions, decimals, and percentages, and remembering to simplify when the answer choices are in simplest form.
Word problems — most questions are scenarios. The math is usually simple; the work is translating English into an equation and answering in the units requested.
What you can mostly skip: factoring polynomials, quadratic equations, the Pythagorean theorem, probability, and scientific notation. The TEAS tests basic "solve for x," not advanced manipulation. If a topic shows up at all, it shows up in one or two questions — review it only after the high-yield list is automatic.
Dosage calculations: the skill that outlives the test
Dosage math is the reason the TEAS math section exists in the form it does. ATI is checking whether you can do basic nursing calculations accurately and quickly — because you will do them every shift, and getting them wrong harms a patient. The core formula is worth memorizing: desired dose / available dose × quantity = amount to administer. If the order is 750 mg and you have 500 mg tablets, then 750 / 500 × 1 = 1.5 tablets. Almost every dosage question reduces to a proportion plus a conversion, which is why those two skills earn their place at the top of your study list.
The metric and dosage conversions to memorize cold
Conversions are free points and they hide inside dosage problems, so missing one can cost you two questions, not one. Memorize these until you do not have to think:
Metric mass — 1 kg = 1,000 g; 1 g = 1,000 mg; 1 mg = 1,000 mcg.
Metric volume — 1 L = 1,000 mL.
Weight (imperial to metric) — 2.2 lb = 1 kg (used constantly for weight-based dosing).
Household volume — 1 tablespoon = 3 teaspoons; 1 cup = 8 fluid ounces.
Use dimensional analysis (the factor-label method) for every conversion, even the easy ones. Write the units in each step and let them cancel: 2.5 kg × (1,000 g / 1 kg) = 2,500 g — the kilograms cancel, leaving grams. This kills the most common conversion error, which is multiplying when you should divide. The math itself tells you which way to go.
Why students struggle (and the fix for each)
Time pressure. 57 minutes for 38 questions feels generous until you are 20 questions deep and behind. Practice timed sets — 10 questions in 15 minutes — until the pace is automatic.
Rusty skills. You learned this once and can relearn it fast, but it takes deliberate practice. Start with the basics, not the prep book glossary.
Word-problem panic. Learn the keyword translations — "of" = multiply, "per" = divide, "more than" = add, "less than" = subtract — and the panic drops.
Answering the wrong question. The question asks for liters; you answer in milliliters. Circle the units requested before you calculate, and check them before you commit.
Rounding too early. Round 0.66 to 0.7 in step two and the final answer is off. Keep full numbers until the end, then round as instructed.

A two-week TEAS math study plan
Week 2 out — drill the high-yield core. Spend two days each on ratios/proportions and conversions, then a day each on percentages and fraction-decimal conversions. Do roughly 10 problems a day per topic, using the same proportion setup and dimensional analysis every time. Build a one-page, handwritten formula and conversion sheet as you go.
Week 1 out — word problems and timed practice. Do 10 word problems a day, circling what each one is solving for. Then take a full timed math section (38 questions, 57 minutes), review every miss, and spend your last few days drilling whatever you missed most.
Final 48 hours — skim and rest. Light review of your formula sheet only — no new material. Sleep, because tired brains make calculation errors, and an all-nighter lowers your score.

TEAS 7 math FAQ
How many math questions are on the TEAS 7?
The Math section has 38 questions — 34 scored and 4 unscored pretest items — and you get 57 minutes, about 90 seconds per question. You will not know which questions are pretest, so answer every one as if it counts.
What math is on the TEAS 7?
Two areas: Numbers & Algebra (18 scored questions — fractions, decimals, percentages, ratios and proportions, basic algebra, and word problems) and Measurement & Data (16 scored questions — metric and household conversions, basic geometry, reading graphs and charts, and mean/median/mode). It is middle-school to early-high-school level, framed in nursing scenarios.
Can you use a calculator on the TEAS math section?
Yes. ATI provides a basic four-function calculator built into the test interface — you do not bring your own. It handles arithmetic, so your job is setting up the problem correctly; the calculator will not save you from a wrong setup or the wrong units.
Is TEAS math hard?
For most students the difficulty is accuracy and time, not the math itself. There is no advanced algebra, complex geometry, or heavy statistics. If you drill ratios, conversions, percentages, and word problems and practice under the clock, the section becomes very manageable.
How do I study for TEAS dosage calculations?
Learn one proportion setup and use it every time, memorize the metric conversions (especially 1 g = 1,000 mg and 2.2 lb = 1 kg), and practice with dimensional analysis so units cancel and tell you which operation to use. Drill realistic dosage scenarios rather than abstract algebra — that is exactly how ATI frames the questions.
Is the TEAS math section harder than the HESI A2 math section?
They test similar fundamentals — ratios, percentages, and conversions — so for most students the difficulty is comparable, and both lean on dosage-style application. The TEAS packs its math into one timed block, while the HESI A2 math is its own separately timed section. If you are choosing between exams, see our TEAS vs HESI comparison.
The bottom line
The TEAS 7 Math section is narrow and predictable: two areas, 34 scored questions, and a handful of topics that carry most of the points. Master ratios and proportions, memorize your metric and dosage conversions, drill percentages and word problems, and practice everything under the clock. You do not need to be a math person — you need a focused plan and two weeks of deliberate practice. Do that, and the section that makes confident students freeze becomes the one that steadies your composite score.
