General Math Test Tutorial

1. Arithmetic Basics
• Operations: Addition, subtraction, multiplication, division.
• Order of Operations: Use PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
• Example: 3 + 6 \times (5 + 4) ÷ 3^2

2. Fractions, Decimals, and Percents
• Conversions:
• Fraction to decimal: Divide numerator by denominator.
• Decimal to percent: Multiply by 100.
• Percent to fraction: Write over 100 and simplify.
• Operations with Fractions:
• Find common denominators to add/subtract.
• Multiply straight across; divide by flipping the second fraction.

3. Algebra Basics
• Solving Equations:
• Isolate the variable:
2x + 5 = 11 → 2x = 6 → x = 3
• Combining Like Terms:
• 3x + 4x - 2 = 5x → 7x - 2 = 5x
• Substitution and Evaluation:
• If x = 2, evaluate 3x^2 + 1 → 3(4) + 1 = 13

4. Geometry Basics
• Perimeter: Add all sides.
• Area:
• Rectangle: A = l \times w
• Triangle: A = \frac{1}{2} \times b \times h
• Circle: A = \pi r^2
• Volume:
• Cube: V = s^3
• Rectangular Prism: V = l \times w \times h

5. Data and Graphs
• Mean (average): Add all values, divide by number of values.
• Median: Middle value.
• Mode: Most frequent.
• Range: Difference between highest and lowest.

6. Word Problems
• Read carefully.
• Define variables.
• Set up an equation.
• Solve and check your work.
