ATI TEAS 7 Math Formulas to Know: Your Ultimate Study Guide
Preparing for the ATI TEAS 7 exam? You need to know the core math concepts. Mastering these formulas is crucial for your success. This guide will detail all the essential ATI TEAS 7 math formulas to know. We will cover algebra, geometry, and data interpretation. For comprehensive preparation, consider prep-exams. They offer excellent resources and practice tests. These tools help ensure you are fully ready.
Understanding the ATI TEAS 7 Math Section
The ATI TEAS 7 math section tests various skills. It covers numbers, algebra, data interpretation, and measurement. You must understand basic operations. Problem-solving is also a key component. The questions are designed to assess your readiness. They determine your ability to apply math in healthcare settings. Strong foundational knowledge is essential. This includes quick recall of formulas. Practice is vital for speed and accuracy.
Essential ATI TEAS 7 Math Formulas to Know: Algebra
Algebra forms a significant part of the TEAS exam. Focus on these key areas and formulas:
- Order of Operations (PEMDAS/BODMAS): Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. This sequence is always followed.
- Solving Linear Equations: Isolate the variable. Use inverse operations. For example, if
x + 5 = 10, thenx = 5. - Fractions:
- Addition/Subtraction: Find a common denominator.
- Multiplication: Multiply numerators and denominators.
- Division: Flip the second fraction, then multiply.
- Decimals and Percentages: Convert between them. Remember,
0.5 = 50% = 1/2. - Ratios and Proportions: Used for comparisons. If
a/b = c/d, thenad = bc. - Exponents: Understand rules like
x^a * x^b = x^(a+b)and(x^a)^b = x^(a*b).
These algebraic principles are fundamental. You will use them throughout the test. Consistent practice builds confidence.
“Success in TEAS math often comes from consistent formula recall. Don’t just memorize them; understand their application in problem-solving scenarios.”
Geometry Formulas You Must Know
Geometry questions will also appear on the TEAS 7. Familiarize yourself with these formulas:
- Area Formulas:
- Square:
side * side(s^2) - Rectangle:
length * width(l * w) - Triangle:
(1/2) * base * height((1/2)bh) - Circle:
pi * radius^2(πr^2)
- Square:
- Perimeter Formulas:
- Square:
4 * side(4s) - Rectangle:
2 * (length + width)(2(l+w)) - Circle (Circumference):
2 * pi * radius(2πr) orpi * diameter(πd)
- Square:
- Volume Formulas:
- Rectangular Prism:
length * width * height(lwh) - Cylinder:
pi * radius^2 * height(πr^2h)
- Rectangular Prism:
- Pythagorean Theorem: For right triangles,
a^2 + b^2 = c^2.cis the hypotenuse.
Visualizing these shapes helps immensely. Drawing diagrams can clarify problems. Remember units are important for area and volume.
Data Interpretation and Measurement Formulas
This section often involves statistics and conversions. Here are some key ATI TEAS 7 math formulas to know:
- Mean (Average): Sum of values / Number of values.
- Median: The middle value in an ordered set. If two middle values, average them.
- Mode: The value appearing most frequently.
- Range: Highest value – Lowest value.
- Conversions:
- Metric System: Understand prefixes like kilo-, centi-, milli-.
- Customary System: Memorize equivalences (e.g., 1 foot = 12 inches, 1 gallon = 4 quarts).
- Time: Conversions between hours, minutes, seconds.
- Temperature: Celsius to Fahrenheit and vice-versa. (
F = C * 9/5 + 32,C = (F - 32) * 5/9)
Data interpretation also involves reading graphs. Practice interpreting bar graphs, pie charts, and line graphs. These skills are critical for healthcare data.
Mastering Ratios, Proportions, and Percentages
These concepts are interwoven throughout the TEAS exam. They are vital for dosage calculations. They are also used for unit conversions. Understanding them deeply is a must.
- Ratios: Expressed as
a:bora/b. Simplify ratios when possible. - Proportions: Two ratios are equal. Use cross-multiplication to solve for unknowns. For example,
1/2 = x/4means2x = 4, sox = 2. - Percentages: ‘Out of 100’. Convert percentages to decimals for calculations. To find 20% of 50, calculate
0.20 * 50 = 10. - Percentage Change:
((New Value - Old Value) / Old Value) * 100%.
Practice word problems involving these concepts. Real-world scenarios are common on the TEAS test. Khan Academy offers free practice.
