TEAS 7 Math Section Breakdown: Dosage, Conversions & Calculator Strategy

Why the Math Section Decides So Many TEAS Scores

Ask nursing students which TEAS section scared them most, and Math wins by a mile. Yet here is the secret tutors at OnlineTEASPrep share with every new student: the TEAS 7 Math section is not advanced math. There is no trigonometry, no calculus, and nothing you have not seen before high school graduation. What makes it hard is the combination of nursing-style word problems, strict timing, and a calculator that is far more limited than the one on your phone.

The good news is that Math is the most learnable section on the entire exam. The same five or six question patterns repeat on every test form. Learn the patterns, drill them under time pressure, and students routinely gain 10 to 20 percentage points in a single week of focused work. This guide breaks down the exact format, every tested topic with worked examples, the formulas worth memorizing, and the calculator strategy that saves points on test day.

TEAS 7 Math Format at a Glance

The Math section gives you 38 questions in 57 minutes, which works out to about 90 seconds per question — the most generous pace of any TEAS section. Not every question counts: 34 are scored and 4 are unscored pretest items mixed in invisibly, so treat every question as if it counts.

Sub-content area	Scored questions	Share of Math score
Numbers and Algebra	18	About 53%
Measurement and Data	16	About 47%
Total scored	34	100%

Most questions are standard multiple choice, but expect a few fill-in-the-blank items where you type the numeric answer with no choices to eliminate from. Those items punish guessing and reward students who set problems up correctly, which is exactly the skill this guide trains.

Numbers and Algebra: The 53 Percent That Matters Most

This sub-area covers arithmetic with fractions and decimals, percentages, ratios and proportions, and solving basic algebraic equations. Because it holds the majority of the points, study it first.

Fractions, Decimals, and Percentages

Fraction questions show up as conversions, ordering, and straight arithmetic. Memorize the decimal equivalents of common fractions and half your work disappears: 1/2 = 0.5, 1/4 = 0.25, 3/4 = 0.75, 1/5 = 0.2, 1/8 = 0.125, and 1/3 ≈ 0.333. When dividing fractions, use Keep-Change-Flip: keep the first fraction, change division to multiplication, and flip the second fraction.

Worked example: A patient drank 3/4 liter of water in the morning and 1/2 liter in the afternoon. How many liters total? Convert to a common denominator: 3/4 + 2/4 = 5/4, or 1 1/4 liters.

Percentage questions usually ask for a percent of a number, a percent change, or a conversion between fractions, decimals, and percents. The percent-change formula is worth memorizing cold: (New − Old) ÷ Old × 100. A clinic's flu vaccinations rising from 200 to 250 patients is a (250 − 200) ÷ 200 × 100 = 25% increase.

Ratios, Proportions, and Dosage Calculations

Cross-multiplication is the single most reusable skill on the section. A proportion sets two ratios equal, and you solve it by multiplying diagonally. Dosage problems are simply proportions wearing a nursing uniform: a doctor orders 500 mg, the tablets are 250 mg each, so 500 ÷ 250 = 2 tablets. The classic nursing formula is Desired ÷ Have × Quantity.

Worked example: An order calls for 250 mg of a drug available as 100 mg per mL. Volume = 250 ÷ 100 × 1 mL = 2.5 mL. Always write the units into your setup. If the units do not cancel to leave the unit the question asks for, the proportion is arranged wrong — that one habit catches most dosage errors before they happen.

Algebra and Order of Operations

Algebra on the TEAS means one-variable equations, translating word problems into expressions, and the occasional inequality. Isolate the variable step by step, and double-check by plugging your answer back in. For order of operations, PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) resolves every expression question. A quick drill: 3 + 4 × (6 − 2)² = 3 + 4 × 16 = 3 + 64 = 67.

Measurement and Data: Where Conversions Win Points

This sub-area covers unit conversions, geometry, reading charts and graphs, and basic statistics. It holds nearly half the Math points, and conversions alone are among the highest-yield facts on the test.

Memorize These Conversions

Conversion	Value	Memory hook
1 kilogram	2.2 pounds	Divide pounds by 2.2 to get kg
1 inch	2.54 centimeters	Exact by definition
1 teaspoon	5 milliliters	Kitchen standard
1 tablespoon	15 milliliters	Three teaspoons
1 fluid ounce	30 milliliters	Dosing-cup standard
1 cup	240 milliliters	Eight ounces
1 liter	1,000 milliliters	Metric ladder
1 kilogram	1,000 grams	Metric ladder

The most common conversion error on the whole section is multiplying pounds by 2.2 instead of dividing. A 154-pound patient weighs 154 ÷ 2.2 = 70 kg, not 339. Convert in single, checkable steps, and sanity-check every answer against real life: an adult human does not weigh 300 kilograms.

Geometry Formulas to Memorize

The TEAS provides no formula sheet, so these must be automatic. Focus on the shapes that actually appear: rectangles, triangles, circles, and boxes.

Shape	Perimeter / Circumference	Area / Volume
Square (side s)	P = 4s	A = s²
Rectangle (l × w)	P = 2l + 2w	A = lw
Triangle (base b, height h)	P = sum of sides	A = ½bh
Circle (radius r)	C = 2πr	A = πr²
Rectangular prism	—	V = lwh
Cylinder	—	V = πr²h

Two traps account for most geometry misses. First, area answers carry squared units — an answer in plain centimeters is wrong before you check the arithmetic. Second, when a problem gives a diameter, halve it before using any radius formula; using the diameter as the radius doubles circumferences and quadruples areas.

Statistics and Data Interpretation

• Mean: the average — add all values and divide by the count.
• Median: the middle value after sorting. With an even count, average the two middle values.
• Mode: the most frequent value.
• Range: largest minus smallest.

Worked example: Test scores of 70, 80, 80, 90, 100. Mean = 420 ÷ 5 = 84. Median = 80. Mode = 80. Range = 100 − 70 = 30. For chart questions, read the labels and units before doing any math — most wrong answers come from misreading the graph, not miscalculating.

Calculator Strategy: Respect Its Limits

The TEAS provides an on-screen four-function calculator for the Math section only. It adds, subtracts, multiplies, and divides — no exponents, no square roots, and critically, no fraction key. Plan around that:

• Use it for multi-step multiplication and division, and for verifying decimal work.
• Skip it for fraction arithmetic you have memorized (1/4 = 0.25) and simple addition or subtraction.
• Convert fractions to decimals first (numerator ÷ denominator) whenever a problem mixes them, since the calculator cannot handle fraction notation.
• Practice with a basic calculator app in standard mode before test day so the stripped-down interface feels familiar instead of strange.

5 Mistakes That Steal Math Points

1. Converting pounds the wrong direction. Divide by 2.2 to reach kilograms. Always.
2. Forgetting to simplify fractions. An unsimplified answer is a wrong answer on the TEAS.
3. Mixing up radius and diameter. Halve the diameter first, every time.
4. Dropping the units. If your setup's units do not cancel to the requested unit, stop and rearrange.
5. Burning 4 minutes on one question. At 90 seconds per question, flag it, move on, and return with fresh eyes if time remains.

Your 2-Week Math Study Plan

• Days 1–3: Fractions, decimals, and percentages. Drill conversions until the common equivalents are instant recall.
• Days 4–6: Ratios, proportions, and dosage. Do 10–15 cross-multiplication problems daily; write units into every setup.
• Days 7–9: Conversions and geometry. Memorize the conversion and formula tables above, then practice mixed sets.
• Days 10–12: Algebra and statistics. Equations, PEMDAS, mean-median-mode-range, and chart reading.
• Days 13–14: Timed mixed sets. Full 38-question blocks in 57 minutes. Keep a miss log: topic, exact cue missed, correct rule, one drill to repeat.

Math rewards depth over breadth. Mastering fractions and proportions first makes dosage, conversions, and half of algebra dramatically easier, because they are all the same underlying skill. Study in that order, practice under a timer, and the section most students fear becomes the section that lifts their composite score.
