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.
