An angle that is less than 90 degrees.
Addition
an adding of two or more numbers to get a number called
the sum
For example:
5+5 = 10
10 is the sum
Algebra
area of math dealing in representing numbers with letters
For example:
x+5=8, solve for x
Algebraic expression
See Expression
Angle
The space (measured in degrees) between two lines that start from the
same point.
Area
The measure of the amount of space a two-dimensional
figure takes up.
For example:Area=length*width
Arithmetic
the art of computing using addition, subtraction, multiplication, and division
Associative
The property that an expression, in a fixed order, will produce the same result no matter how adjacent items are grouped.
For example:
(a+b)+c = a+(b+c)
A graph that uses separate bars (rectangles) of different heights (lengths) to show and compare data
Binomial
A polynomial with two terms.
For example:
(2x+3)
A method of calculation. One of several highly systematic methods of treating problems by a special system of algebraic notations.
Circle
a curved line with every point equal distance from the centre
Circumference
The length of the outer boundary of a circle.
For example:Circumference=Pi*Diameter.
Compass
An instrument used for drawing circles, describing circles, or measuring distances. Consists of two hinged, movable legs.
Compliment
In probability, the complement of an event is all outcomes
different from the favorable outcome. The sum of the probability of an
event and its complement is 1.
For example:
The number cube is labeled 1-6.
Complementary Angle
Either of two angles that when added together produce an angle of 90 degrees.
Composite Number
any integer that can be divided by another number evenly
except by itself and 1
For example:"21, 24, 9, 10"
Congruent
Having the same size and shape, equal; equal angles are described to be this
Coordinate Axis
two perpendicular lines intersecting to form four quadrants
Cubic Centimeter (cm³)
A metric unit of volume; the volume of a cube 1 centimetre on a side. 1 cubic centimetre is equal to 1 millilitre.
A number that uses place value and a decimal point to
show tenths, hundredths, thousandths, and so on
For example:
3.47
Dekametres
A unit of length that is equal to 10 meters.
Denominator
The bottom number in a fraction
For example:15/16 16 is the denominator
Density
Mass per unit volume of a substance.
For example:Units: g/cm3 or g/ml
Diameter
The measurment of a line that passes from one side of a circle to the other side of the circle, through the center point.
Difference the amount by which one number differs from
another
For example:9-8=1 the difference of 9 and 8 is 1
Dividend
the number being divided
For example: 12÷3=4
12 is the dividend
Divisible
Capable of being evenly divided by a number, without a remainder.
Division
the process of finding out how many times a number is
contained in another
For example: 6÷3=2
3 goes into 6 two times
Divisor
the number doing the dividing
For example:
12÷2=6
2 is the divisor
The number used as the base for natural logarithms. Equal to "2.7182818..."
Ellipse
a curved line with the sum of the distances from imaginary points (foci)
to each point on the curve is constant
Equation
An algebraic expression asserting the equality of two
quantities.
For example :
x + 4 = y -10
Equilateral
A figure with all it's sides equal in length.
For example:
A square is equilateral
Equilateral Triangle
A triangle with all sides and angles equal in length.
Estimate
An approximate calculation of the value of something.
Exponent
a small figure placed to the upper-right of a number showing the number of times to multiply that number by itself
A mathematical symbol, or combination of symbols, representing
a value, or relation. An expression is usually written using one or more
variables such as x or y
For example:
3x, x – 4
or 2a + 5
or a + b
