UltimateGED.com - GED Math 2024 Test Preparation

Key Points from Video

General Strategy

• Best preparation for the GED math test is to practice with standard GED test questions.

Specific Topics Covered

1. Translating Word Problems into Algebraic Expressions

• Example: "Product of seven and a number increased by 5 is 30" translates to the algebraic expression 7x + 5 = 30.

2. Coordinate Plane and Identifying Shapes

• Plotting points and connecting them to form shapes; for example, plotting points and forming a rectangle.

3. Volume of a Cylinder

• Formula: \(\pi r^2 h\). To find the volume, understand the formula and apply given dimensions.

4. Slope and Y-Intercept

• The slope-intercept form of a line: \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept.

5. Simple Interest Calculation

• Formula: \(PRT\) (Principal \(\times\) Rate \(\times\) Time). Apply formula to calculate the interest over a given period.

6. Finding Years for Loan Repayment

• Rearrange and solve the simple interest formula to find the time necessary to repay a loan.

7. Calculating Slope from Points

• Formula: \(\frac{y_2 - y_1}{x_2 - x_1}\). Select two points and apply the formula to find the slope.

8. Solving Two-Step Equation Word Problems

• Understanding and solving equations based on grouped items, such as boxes or containers, and remaining quantities.

9. Simplifying Algebraic Expressions

• Techniques for expanding and simplifying expressions, including distributing negatives and combining like terms.

10. Applying the Pythagorean Theorem

• Using \(a^2 + b^2 = c^2\) to find missing sides in right triangles.

11. Consecutive Integers and Products

• Solving problems involving products of consecutive integers either through logical reasoning or algebraic expressions.

12. Mean, Mode, and Median

• Methods to find the mean (average), mode (most frequent value), and median (middle value) of a data set.

13. Scoring for Graduation

• Using averages to determine what score is needed on a final test to achieve a desired overall average.
