Study Notes

Mathematical Terms and Concepts

Base: The foundational number used as a factor in exponential notation, indicating how many times the number is multiplied by itself.
Compare: The process of evaluating and analyzing differences between numbers or quantities to determine their relationship (greater than, less than, or equal).
Decimal: A numeric representation that includes a decimal point, showing values less than one through digits placed to the right of the point.
Decimal Point: The symbol that separates the whole number part from the fractional part in decimal notation.
Decimal Place-Value Chart: A visual representation that organizes decimal digits in order according to their place values, helping in understanding their significance in a number.
Digit: Basic numerical symbols (0 through 9) that are combined to create numbers.
Equivalent: Refers to two or more numbers or quantities having the same value; this can refer to equal fractions or decimal representations.
Equivalent Decimals: Different decimal representations that express the same quantity or value, such as 0.5 and 0.50.
Expanded Form: A method of expressing a number that highlights the value of each digit based on its place within the number (e.g., 231 = 200 + 30 + 1).
Exponent: A numerical notation indicating how many times the base is multiplied by itself; critical in exponential operations.
Factor: Whole numbers that are multiplied together to produce a product; essential in understanding multiplication concepts.
Greater Than (>): An inequality symbol indicating that the number on the left is larger than the number on the right, pointing away from the greater value.
Greatest to Least: A method of arranging numbers on a number line or in a set, starting with the highest value and moving to the lowest.
Halfway: The exact middle value between two given points or numbers, especially relevant in measurements and averaging.
Hundredths: A unit in decimal notation representing one part of 100 equal divisions of a whole; foundational for understanding fractions and decimals.
Increase: An action that makes a quantity larger or adds value, critical in arithmetic operations and real-world applications.
Least to Greatest: The arrangement of numbers from the smallest to the largest on a number line or in a sequence.
Less Than (<): An inequality symbol showing that the number on the left is smaller than the number on the right.
