Section 1
(50 cards)
Base
In exponents, it is the number you multiply repeatedly Ex. 2 is the base: 2 x 2 x 2
Sum
The answer to an addition problem
Product
The answer to a multiplication problem
Constant
A term that is only a number; it has no variable attached to it. It is called this because its value never changes. Example: In 2n + 6, it is the 6
Compsite Numbers
#s having 3 or more factors Ex. 12= 1, 2, 3, 4 6, 12
Rectangular Prism
A polyhedron made up of rectangles (and possibly some squares)
Base
Any one of the sides of a triangle but it is often the side it "sits" on
Evaluate
To substitute a number for a variable and simplify
Inequality
A mathematical sentence containing >, <, ≥, ≤ symbols Has INFINITE number of solutions
Dimensions
The measurements of a shape. Ex. Length, Width, height or Base, Height
Numerical Expression
An expression only made up of numbers Ex. 9 + 3 x 2
Least Common Multiple
The smallest multiple 2 or more numbers share List multiples and find smallest in common
Fraction
Represents a part of a whole
Distributive Property
Math property that allows you to multiply a common factor by a sum of a number 5(2 + 6) = 5(2) + 5(6)
Formula for finding Area of a Rectangle, Square or Parallelogram
A = BH A= LW
Operations
Adding, Subtracting, Multiplying, Dividing
Decompose
To break apart
Exponent
The number that tells you how many tiems the base is being multiplied by itself. Ex. The 2 tells 5 to multiply itself 2 times: 5 x 5
Formula for finding volume of a rectangular prism
V = LWH Label is "units cubed" or "cubic units"
Formula for finding Area of a Triangle
A = ½ BH
Divisor
In division, it is the number doing the dividing
Like Terms
Terms that can be combined together. They can be: -Constants -Terms that have the same last name (combination of variables) Examples: 2 + 2n + 3 + 5n; 2 and 3 are this and 2n and 5n are this.
Factors
The numbers you multiply to get a product
Congruent
Figures with the EXACT same shape and size.
Compose
To create something new by putting shapes together to make new shapes
Variable
A symbol that represents a number. This symbol is usually a letter and its value can vary. Example: The n in 2 + n
Greatest Common Factor
The largest factor 2 or more numbers share List factors & find greatest in common
Equation
When two expressions are equal; a math sentence with an EQUAL sign. Ex. 10n = 20
Simplifying
Putting an expression in its simplest form (possibly solving or putting together like terms) Example: 2 + 8n + 7 + 2n + 4mn is the same as saying 9 + 10n + 4mn
Surface Area
The total surface are of all the faces of a polyhedron. Find the aera of each face and add them up.
Exponential Form
Writing a number in a form that shows the base and the exponent
Inverse Operations
Opposite operation that "undo" each other. Ex. Addition/Subtraction and Multiplication/Division
Dividend
In division, it is the number being divided
Multiples
The product of a number and another whole number. Ex. 25 = 25, 50, 75, ...
Co-efficient
In a term, it is the number that appears before the letter. Its total value depends on what the variable is equal to. If there is a - sign before it, you must attach it Example: In 2n, it is the 2 Example: 3 - 2n, it is the -2
Difference
The answer to a subtraction problem
Equivalent
Another word for "Equal"
Quotient
The answer to a division problem
Terms
In an expression, they are the parts separated by a plus or minus sign. They can be numbers, variables or the product of a number/variable Example: In 2ab + c, it is the 2ab and the c
Formulas for finding Perimeter
P = s + s + s + ... (any shape) P = 4s (square) P = 2L + 2W (rectangle)
Net
A flattened version of a polyhedron that can be folded to make the 3-d shape.
Factors
#s you multiply together to get a product OR #s that divide evenly into another number Ex. 15= 1, 2, 5, 15
Expression
1 or more terms combined by a +/- sign. NO EQUAL SIGN. Example: 10n+8
Height
The distance from the top vertex of a triangle or parallelogram to its base.
Set
A list of numbers to choose from; Usually inside brackets.
Cubed
A number with an exponent of 3
Area
The space INSIDE a 2D shape
Prime Numbers
#s have exactly 2 factors; 1 and itself Ex. 5= 1 and 5
Squared
A number with an exponent of 2
Order of Operations
Grouping Exponent Multiplication & Division (left to right) Subtraction & Addition (left to right) Ex. 2 + 3(4 + 2 x 4) 2 + 3 (4 + 8) 2 + 3(12) 2 + 36 38
