It allows you to tackle problems efficiently. This speed is critical for completing the section. Accuracy also improves significantly.
Formulas provide a structured approach. They eliminate guesswork. You apply a known rule. Then you solve the problem directly. This reduces test anxiety. It builds confidence in your answers. A solid grasp of ATI TEAS 7 math formulas to know is a game-changer. It truly sets successful students apart.
Foundational ATI TEAS 7 Math Formulas to Know: Arithmetic and Algebra
Let’s dive into the core formulas. These form the building blocks. They are essential for almost every question type.
Basic Operations & Order of Operations
Remember PEMDAS. This acronym guides calculations.
- P: Parentheses
- E: Exponents
- MD: Multiplication and Division (from left to right)
- AS: Addition and Subtraction (from left to right)
Example: 2 + 3 * (5 - 1)
First, (5 - 1) = 4.
Then, 3 * 4 = 12.
Finally, 2 + 12 = 14.
Fractions, Decimals, Percentages
You will convert between these often.
- Fraction to Decimal: Divide numerator by denominator. (e.g.,
1/2 = 0.5) - Decimal to Percentage: Multiply by 100. (e.g.,
0.5 * 100 = 50%) - Percentage to Decimal: Divide by 100. (e.g.,
50% / 100 = 0.5) - Percentage of a Number: Convert percent to decimal. Multiply by the number. (e.g.,
20% of 60is0.20 * 60 = 12) - Percent Change:
((New Value - Old Value) / Old Value) * 100
Ratios, Proportions, Rates
These concepts are fundamental.
- Ratio: Compares two quantities. (e.g.,
3:2or3/2) - Proportion: Two ratios are equal. (e.g.,
a/b = c/d)- To solve proportions, cross-multiply:
a * d = b * c.
- To solve proportions, cross-multiply:
- Rate: Ratio with different units. (e.g., miles per hour)
- Distance = Rate × Time
- Rate = Distance / Time
Algebraic Expressions & Equations
Algebra skills are tested heavily.
- Solving Linear Equations: Isolate the variable.
- Example:
2x + 5 = 15 - Subtract 5 from both sides:
2x = 10 - Divide by 2:
x = 5
- Example:
- Solving Basic Inequalities: Similar to equations.
- Remember to flip the inequality sign. Do this if you multiply or divide by a negative number.
- Slope Formula:
m = (y2 - y1) / (x2 - x1)(useful for graphing)
Geometry Formulas for the ATI TEAS 7 Exam
Geometry appears frequently. Knowing these shapes and their properties is key.
Area and Perimeter
- Square:
- Perimeter:
4s(s = side length) - Area:
s²
- Perimeter:
- Rectangle:
- Perimeter:
2(l + w)(l = length, w = width) - Area:
l * w
- Perimeter:
- Triangle:
- Perimeter:
a + b + c(sum of sides) - Area:
(1/2) * b * h(b = base, h = height)
- Perimeter:
- Circle:
- Circumference (Perimeter):
2πrorπd(r = radius, d = diameter) - Area:
πr²
- Circumference (Perimeter):
Volume
- Cube:
s³ - Rectangular Prism:
l * w * h - Cylinder:
πr²h
Pythagorean Theorem
This applies to right triangles only.
a² + b² = c²(a, b are legs, c is hypotenuse)- This helps find unknown side lengths.
Angle Relationships
- Angles on a Straight Line: Sum to 180 degrees.
- Angles in a Triangle: Sum to 180 degrees.
- Vertical Angles: Are equal.
Data Interpretation and Measurement Formulas
These are vital for healthcare professionals. They are also common on the TEAS exam.
Measures of Central Tendency and Spread
- Mean (Average):
Sum of all values / Number of values - Median: The middle value in an ordered set.
- If even number of values, average the two middle numbers.
- Mode: The most frequent value.
- Range:
Highest value - Lowest value
Probability
- Basic Probability:
(Number of favorable outcomes) / (Total number of possible outcomes)
Unit Conversions (Metric & Imperial)
Be prepared to convert between systems.
- 1 inch = 2.54 cm
- 1 foot = 12 inches
- 1 yard = 3 feet
- 1 mile = 5280 feet
- 1 pound ≈ 0.45 kg
- 1 kg ≈ 2.2 pounds
- 1 fluid ounce ≈ 30 mL
- 1 cup = 8 fluid ounces
- 1 pint = 2 cups
- 1 quart = 2 pints
- 1 gallon = 4 quarts
- 1 liter ≈ 1.057 quarts
Remember to set up conversion factors. Use dimensional analysis.
