ISEE Upper Level Quantitative Reasoning focuses on developing advanced mathematical skills and problem-solving abilities for high school students.
Numbers are the foundation of all mathematics. They come in different types, including whole numbers, integers, fractions, decimals, and percents. Each type of number plays a unique role in problem solving.
The four basic operations—addition, subtraction, multiplication, and division—are used to manipulate numbers. Remember the order of operations (PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) to solve expressions correctly.
Fractions and decimals often appear on the ISEE. Converting between them, comparing their sizes, and performing operations are essential skills.
Imagine you are budgeting for a class event. You need to add up costs, split bills, and calculate discounts—these all rely on solid number sense and operational skills.
If a pizza is cut into 8 slices and you eat 3, what fraction of the pizza did you eat? You ate \( \frac{3}{8} \) of the pizza.
Convert 0.75 to a fraction: \( 0.75 = \frac{3}{4} \).
Mastering how to use and operate with different types of numbers is key to solving quantitative problems.
