Count : To count means to find out the number of objects by adding one for every object.

Standard algorithm : By standard algorithm we refer to any one of the algorithms that are commonly taught at school to add, subtract, multiply or divide multi-digit numbers such as long division and partial products multiplication.

Subtraction : Subtraction is the mathematical operation that describes decreasing a number by an amount equal to a second number. The mathematical symbol for subtraction is the minus sign $-.$ The term subtraction is also used for a generalization of this basic operation on numbers to functions, vectors and matrices.

Bound : A bound refers to a level that is not exceeded by a function or sequence (upper bound) or a level that a function or sequence does not go below (lower bound). For example the function $f(x)=x^2$ has a lower bound of 0 but no upper bound. The function $f(x)=\sin x$ has an upper bound of 1 and a lower bound of -1.

Cubed : The cube of a number $x$, or $x$ cubed or $x^3$ is the third power of $x$: $x^3=x\cdot x\cdot x.$ For example 2 cubed equals 8.

Even : Even can refer either to an even function or an even number.

Function : A function is a mapping in which every element in one set is mapped to exactly one element of a second set. Most often the mapping is described using a rule. For example the function $f(x)=x+1$ maps 2 to 3 and -1 to 0.

Graph : The graph of a function is the set of points $\{(x,f(x))\}$ that can be blotted in a coordinate system.

Odd : In mathematics odd can refer either to an odd function or an odd number.
