Hundred : Hundred refers to the number 100.
Partial products method : A method for calculating a product of two multi-digit numbers by writing both numbers as a sum of ones, tens, hundreds and so on, then multiplying each pair of terms and finally summing up all the terms. For example $12\cdot 34=(10+2)\cdot(30+4)$ $=10\cdot 30+10\cdot 4+2\cdot 30+2\cdot 4$ $=300+40+60+8=408.$

Angle : If two line segments (or rays) both start at a common point the opening between the two line segments is called an angle. The common point is called vertex of the angle. The size of an angle is measured in degrees.
Degree : For angles one degree is defined as the angle represented by a $\frac{1}{360}$ of the angle represented by a full circle. For measuring temperatures one can use either degrees Celsius or degrees Fahrenheit. In a polynomial the degree describes the highest exponent of $x$ that has a non-zero coefficient. For example the degree of $1+x+x^2$ is 2.
Interior angle : An interior angle at the crossing of two parallel lines by a third line means any of the angles between the two parallel lines. An interior angle of a polygon is any of the angles at any of the corners of the polygon that lies within the polygon.
Pentagon : A pentagon is a polygon with five corners. The sum of the angles in a pentagon is $540^{\circ}.$
Regular polygon : A polygon is called regular if it is convex, equilateral and equiangular.
Sum : A sum is the result of an addition.
Triangle : A triangle is a polygon with three corners and three sides. You can calculate the area of a triangle by multiplying half the length of the base by the height on that base. The sum of the interior angles in a triangle is always $180^{\circ}.$
How many degrees are in any of the 5 interior angles of a regular pentagon?
Addition : Addition is the mathematical operation that describes increasing a number by an amount equal to a second number. The mathematical symbol for addition is the plus sign $+.$ The term addition is also used for a generalization of this basic operation on numbers to functions, vectors and matrices.
Zero : The number 0.
