Below you’ll find a list that includes some staple words like Calculate and Circle, as well as words like Conjugate and Cubed that are important in the science of math:

## Math Words That Start With C

**Calculate **– to use math or logic to figure out a problem.

**Calculus **– branch of mathematics concerned with the calculation of instantaneous rates of change (differential calculus) and the summation of infinitely many small factors to determine some whole (integral calculus).

**Calendar **– A diagram that shows what day and month it is.

**Cancel **– to remove or simply that particular value or expression by subtracting, or dividing with a common term.

**Capacity **– used when measuring how much fluid fits inside a container.

**Capital Gain** – the amount of money gained from the sale of an asset.

**Capital Loss** – the amount of money lost or the decrease in value of an asset.

**Cardinal Number** – a number (such as 1, 5, 15) that is used in simple counting and that indicates how many elements there are in an assemblage.

**Cash Flow **– the money that comes in and goes out of a company.

**Catenary **– a curve that describes the shape of a flexible hanging chain or cable—the name derives from the Latin catenaria (“chain”).

**Census **– Collection of data from a whole population rather than just a sample.

**Circle **– a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”.

**Circumference **– the length of any great circle, the intersection of the sphere with any plane passing through its center.

**Clockwise **– Moving in the direction of the hands on a clock.

**Coaxial **– In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis.

**Coefficient **– a number multiplied by a variable.

**Coincident **– the coincident lines are lines that lie upon each other in such a way that when we look at them, they appear to be a single line, instead of double or multiple lines.

**Collinear **– Three or more points are said to be collinear if they all lie on the same straight line.

**Column Graph **– a graph which uses bars to show values so they can be easily compared.

**Commission **– a percentage of total sales as determined by the rate of commission.

**Common Denominator** – a common multiple of the denominators of several fractions.

**Common Factor **– a number that can be divided into two different numbers, without leaving a remainder.

**Common Logarithm **– the common logarithm is the logarithm with base 10.

**Common Multiple **– a multiple of each of two or more numbers or expressions.

**Compass **– an item used in mathematics for drawing and drafting to create arcs, circles or other geometric figures that can be determined by measuring intersecting line segments.

**Complex Fraction **– a fraction in which the numerator or the denominator or both contain one or more fractions.

**Complex Number **– Complex numbers are numbers that consist of two parts — a real number and an imaginary number.

**Compound Interest **– Compound interest is the interest paid on the original principal and on the accumulated past interest.

**Compounding **– to make (something, such as an error or problem) worse : to add to (something bad) He compounded [=exacerbated] his mistake by announcing it to the whole table.

**Computer **– When you solve a mathematical problem, you compute the answer.

**Concave **– Concave describes shapes that curve inward.

**Conclusion **– a judgment or decision reached by reasoning.

**Cone **– the surface traced by a moving straight line (the generatrix) that always passes through a fixed point (the vertex).

**Congruent **– a term employed in several senses, each connoting harmonious relation, agreement, or correspondence.

**Conical **– An object that is shaped like a cone is said to be ‘conical’.

**Conjugate **– formed by changing the sign between two terms in a binomial.

**Conjunction **– When two statements are combined with an ‘and,’ you have a conjunction.

**Constant **– any well-defined real number which is significantly interesting in some way.

**Contagent **– a proposition that is neither a tautology nor a contradiction.

**Converge **– approaching a limit more and more closely as an argument (variable) of the function increases or decreases or as the number of terms of the series increases.

**Convert **– To change a value or expression from one form to another.

**Convex **– A function is said to be convex when the function has a slope that is increasing.

**Coordinates **– A point on a grid has two numbers to identify its position.

**Correlation **– When two or more sets of data are linked together, they have a high correlation.

**Cosecant **– a trigonometric function that for an acute angle is the ratio between the hypotenuse of a right triangle of which the angle is considered part and the leg opposite the angle.

**Cosh **– The Math.cosh() function returns the hyperbolic cosine of a number that can be expressed using the constant e: Math.cosh(x) = e x + e – x 2.

**Cosine **– the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.

**Counterclockwise **– Moving in the opposite direction to the hands on a clock.

**Covariance **– the measure of the joint variability of two random variables.

**Cramer’s Rule** – an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution.

**Credit **– the ability to borrow money or access goods or services with the understanding that you’ll pay later.

**Critical Number** – tell you the points where the graph of a function changes direction.

**Crore **– denotes ten million (10,000,000 or 10power7 in scientific notation).

**Cross Multiply **– to clear an equation of fractions when each side consists of a fraction with a single denominator by multiplying the numerator of each side by the denominator of the other side and equating the two products obtained.

**Cube **– A cube number is a number multiplied by itself 3 times.

**Cubic Measure** – In geometry, cubic units can be defined as the units used to measure volume.

**Cuboid **– a solid shape with six rectangular surfaces or four rectangular and two square surfaces.

**Curve **– an abstract term used to describe the path of a continuously moving point.

**Cylinder **– A cylinder is a three-dimensional solid figure which has two identical circular bases joined by a curved surface at a particular distance from the center which is the height of the cylinder.
