Math Definitions for Pearson
Place value
determines the value of a digit in a number, based on the location of the digit.
Factors
The numbers multiplied together to find a product. EX: 3*6 =18
Estimating
to form an approximate judgment or opinion regarding the worth, amount, size, weight,
etc., of; calculate approximately:
Consecutive Integers
An integer is simply a number like 0, 1, 2, 3, and 4, but unlike whole numbers, integers
also include negative numbers like -1, -2, -3 and -4. An integer cannot be a decimal or a
fraction.
Integers
are the set of whole numbers and their opposites. Whole numbers greater than zero are
called positive integers. Whole numbers less than zero are called negative integers. The
integer zero is neither positive nor negative, and has no sign.
Scientific Notation
a method for expressing a given quantity as a number having significant digits
necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power,
as 1385.62 written as 1.386 × 10 3.
Rounding
replacing a number with a number that tells about how many or how much.
Rational Numbers
is any number that can be expressed as the quotient or fraction p/q of two integers, p
and q, with the denominator q not equal to zero.
Exponents
, A number placed above and to the right of another number to show that it has been
raised to a power. For example, 32 indicates that 3 has been raised to a power of 2, or
multiplied by itself; 32 is equal to 9.
Prime Factorization
A Prime Number can be divided evenly only by 1 or itself.
Greatest Common Factor
is the greatest factor that divides two numbers.
Inequalities
a number sentence that uses the greater than sign (>) or the less than sign (<) to show
that two expressions do not have the same value.
Lowest Common Multiple
The smallest positive number that is a multiple of two or more numbers. Example: the
Least Common Multiple of 3 and 5 is 15, because 15 is a multiple of 3
Number Lines
is a straight line with a "zero" point in the middle, with positive and negative numbers
listed on either side of zero and going on indefinitely. An example of a number line is
what a math student can use to find the answer to addition and subtraction questions.
Simplifying Fractions
a fraction in which thee numerator and denominator have no common factors other than
1.
Percents
is part of something, split into a hundred pieces. For example, fifty percent of forty is
twenty.
Repeating Decimals
number that has digits that repeat forever. Examples: 1/3 = 0.333... (the 3 repeats
forever)
Ratio & Proportions
A proportion is a name we give to a statement that two ratios are equal. It can be ...
When two ratios are equal, then the cross products of the ratios are equal.
Absolute Value
