ISEE Upper Level Quantitative Reasoning focuses on developing advanced mathematical skills and problem-solving abilities for high school students.
Inequalities show how values compare, using signs like \( <, >, \leq, \geq \). Absolute value is the distance a number is from zero, always positive.
The steps are similar to solving equations, but remember to flip the inequality sign when multiplying or dividing by a negative number!
Absolute value is used to measure distances, like how far a temperature is from freezing, regardless of direction.
Inequalities are great for budgeting ("I have less than $20 to spend"), and absolute value helps in tracking changes, like temperature drops.
Solve \( x - 4 > 3 \): Add 4 to both sides to get \( x > 7 \).
The absolute value of -6 is 6 because it's 6 units from zero.
Inequalities compare values, and absolute value measures how far a number is from zero.
