NES 103 Math
composite number
A natural number greater than 1 that can be evenly divided by at least one other number besides 1 and itself. EX: 6 can be divided by 1, 2, 3 and 6
irregular polygon
A polygon where the sides and angles are not the same.
concave polygon
A polygon with at least one diagonal outside the polygon.
convex polygon
A polygon with no diagonal lines outside the polygon.
3 dimensional object
An object that has height, width and depth.
the zero power 4^0
Any number with a zero exponent equals one.
nonstandard units of measurement
Aren't typically used for measurement. EX: a pencil, an arm, a toothpick, or a shoe
2 dimensional object
Has two dimensions (such as width and height) and no thickness. EX: Squares, Circles, Triangles
associative property
In multiplication and division, the answer will remain the same regardless of where the parenthesis are placed. EX: (a+b)+c=a+(b+c)
distributive property
Lets you multiply a sum by multiplying each addend separately and then add the products. EX: a(b + c) = ab =ac
rational numbers
Numbers that can be made by dividing 2 integers. Includes fractions or terminating/repeating decimals. EX: 0.125
natural numbers
Numbers used in counting. EX: 1,2,3...
inverse operations
Operations that cancel out the other operation. EX: 2+3=5 5-3=2
integers
Positive and negative whole numbers.
whole numbers
Similar to natural numbers, but includes 0.
degrees
The exponents in a polynomial
coefficients
The numbers before the exponent in a polynomial. EX: 4x^ + 5x^ + 1, 4 and 5 - 1 is a constant
standard unit of measurement
Typically used within each measurement system. EX: inches, feet, ounces, pounds, kilograms, cups
independent variables
Values that determine the value of other variables. EX: y = 3x - 2, the independent variable is x
dependent variables
Variables whose value depends on other variables. Usually this variable is isolated on one side of an equation. EX: y = 3x - 2, the dependent variable is y. The value of y depends on the value chosen for x.
