power
乘方
numeral
A symbol used to represent a number
calculus
A branch of mathematics in which calculations are made using special symbolic notations; developed by Isaac Newton
addition

divide
÷
quantity
An amount that can be counted or measured.
cone
A three dimensional shape with a circular base and a vertex opposite the base
degree
A unit used to measure distances around a circle. One degree equals 1/360 of a full circle.
volume
A measure of the size of a body or region in three-dimensional space
abacus
a calculator that performs arithmetic functions by manually sliding counters on rods or in grooves
square root
The square root of a number n is a number which, when multiplied by itself, results in the number n. For example, 4 is a square root of 16, because 4*4=16.
parallel
lines that are parallel are the same distance apart at every point along their whole length
multiplication table
a table used to find the product of two numbers
decimal
A number less than a whole number
plus
+
subtraction
Arithmetic operator that subtracts contents of cells
equation
A mathematical sentence that shows that two expressions are equivalent
oblong
a shape that is longer than it is wide
rectangle
A parallelogram with 90 degree angles. A square is also a rectangle.
aggregate
Sum Total
circle
A round plane figure whose boundary consists of points equidistant from the center
mathematics
数学
right angle
90 degree angle
division
a calculation in mathematics of how many times a number is contained in a larger number
radius
A straight line from the center to the circumference of a circle or sphere.
polygon
A closed figure formed by three or more line segments
area
Length x Width
cube root

minus
-
multiplication
the process of adding a number to itself a particular number of times
circumference
The distance around a circle
cube
