The sum is the answer to an ADDITION problem. 3+4=7 The sum of 3 and 4 is 7. ^ sum | |
The difference is the answer to a SUBTRACTION problem. 8-5=3 The difference between 8 and 5 is 3. ^ difference | |
The product is the answer to a MULTIPLICATION problem. 5*7=35 The product of 5 and 7 is 35. ^ product | |
The quotient is the answer to a DIVISION problem. 48/6=8 The quotient of 48 and 6 is 8. ^ quotient | |
ratio | 1. Relation in degree or number between two similar things. 2. 3. Mathematics A relationship between two quantities, normally expressed as the quotient of one divided by the other: The ratio of 7 to 4 is written 7:4 or 7/4. |
proportion Example: number of miles driven is proportional to the amount of gasoline used | In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other. Example: 3 is related to 12 in the same way that 8 is related to 32 because 3*4=12 and 8*4=32. This situation is proportional. |
probability 0% probability = no chance 100% probability = absolute chance 50% probability = equally likely to occur or not occur | Probability is a way of expressing knowledge or belief that an event will occur or has occurred. The concept has been given an exact mathematical meaning in probability theory, which is used extensively in such areas of study as mathematics, statistics, finance, gambling, and science. |
area For rectangles, area = length * width or A = lw | Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. |
volume Example: The volume of the swimming pool is 480 cubic feet. | Volume is how much three-dimensional space a substance (solid, liquid, gas, or plasma) or shape occupies or contains. |
surface area | Surface area is the measure of how much exposed area a solid object has, expressed in square units. |
Mathematics To calculate the numerical value of; express numerically. To evaluate 3x+4 for x=2, calculate 3(2)+4=6+4=10. | |
expression - several or many products or quotients added with or subtracted from one another | |
percent | In mathematics, a percentage is a way of expressing a number as a fraction of 100 (per cent meaning 'per hundred' in Latin). It is often denoted using the percent sign, '%', or the abbreviation 'pct'. For example, 45% (read as 'forty-five percent') is equal to 45/100, or 0.45. |
Markup is the difference between the cost of a good or service and its selling price. A markup is added on to the total cost incurred by the producer of a good or service in order to create a profit. | |
A discount is a 'mark down.' Discounts are reductions to a basic price of goods or services. | |
parallelogram | In geometry, a parallelogram is a quadrilateral with two pairs of parallel sides. A parallelogram is formed from the intersection of 2 sets of parallel lines. |
trapezoid | In geometry, a four-sided figure with one pair of parallel sides is referred to as a trapezoid. A trapezoid is formed from the intersection of one set of parallel lines and one set of nonparallel lines. |
radius | In classical geometry, a radius of a circle or sphere is any line segment from its center or axis of symmetry to its perimeter. |
diameter | Two radii OR the distance completely across a circle and through the center of a circle. |
The circumference is the distance around a closed curve, usually a circle. Circumference is a special perimeter. | |
the distance around the shape OR the sum of all the sides of a straight-edged shape |
