PLM College Entrance Exam Reviewer - Math and Abstract Reasoning

Practice flashcards based on the PLM College Entrance Exam Reviewer covering Abstract Reasoning rules, Math rules, and practice topics.

What should you look for when analyzing number sequences in abstract reasoning?

Look for addition, subtraction, multiplication, division, or changing differences.

How should letter sequences be analyzed in abstract reasoning?

Use alphabet positions and check whether letters move forward or backward.

What is the rule for solving analogy questions in abstract reasoning?

Identify the relationship in the first pair and apply it to the second pair.

What is the goal when solving odd one out questions in abstract reasoning?

Find the item that does not follow the same category or pattern.

What is the rule for coding and decoding questions?

Follow the letter/number pattern given in the question.

What constraint must be followed in logical reasoning?

Use only the information given; do not assume extra information.

According to the MDAS rule, which operations take precedence?

Multiplication and Division come before Addition and Subtraction.

What step must be completed first when adding or subtracting fractions?

Make denominators the same first.

How is the percentage of a number calculated?

$$\text{Percentage of a number} = \text{decimal form of percentage} \times \text{number}$$

What are the formulas for calculating discount and sale price?

$\text{Discount} = \text{original price} \times \text{discount rate}$ and $\text{Sale price} = \text{original price} - \text{discount}$

How is average defined in the Math rules?

$$\text{Average} = \text{sum of all values} \div \text{number of values}$$

How should proportions be solved in ratio and proportion problems?

Keep equivalent ratios equal and cross-multiply when solving proportions.

What strategy is used in algebra to isolate the variable?

Use inverse operations to isolate the variable.

What should be done when a number multiplies a parenthesis in math problems?

Simplify or distribute correctly when a number multiplies a parenthesis.

What are the geometric formulas for the area and perimeter of a rectangle?

$\text{Rectangle area} = \text{length} \times \text{width}$ and $\text{Perimeter} = 2(\text{length} + \text{width})$

What is the formula for the area of a triangle?

$$\text{Triangle area} = \frac{1}{2} \times \text{base} \times \text{height}$$

What step should be taken before guessing the rule for number patterns?

Check the differences between consecutive numbers before guessing the rule.

What practice topics are listed under Abstract Reasoning?

Number sequences, letter sequences, analogies, odd one out, coding/decoding, logical reasoning, and pattern recognition.

What practice topics are listed under Math?

Basic operations, MDAS, fractions, decimals, percentages, discounts, average, ratio/proportion, algebra, linear equations, exponents, geometry, word problems, and number patterns.
