Decimal part of a whole number expressed as digits placed to the right of a decimal point Difference the result of subtracting one number from another Digit Any of the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Dividend In a division problem, the number being divided is the dividend. Divisor In a division problem, the number that is divided into another number is the called the divisor. Equation A mathematical statement that indicates that the value of two mathematical expressions are equal. Fraction A portion of a whole number represented by two numbers. The upper number is the numerator and the bottom number is the denominator. Negative numbers Numbers less than 0. Place value The exact value a digit represents in a whole number, determined by its place within the whole number or by its position relative to the decimal point. Positive numbers Numbers that are greater than zero. Product The answer to a multiplication problem Quotient The result of a division problem. For example, when dividing 6 by 2, the quotient is 3. Remainder The amount left over when one number is divided by another. Sum The resulting total in an additional problem Whole numbers Complete number units without fractions or decimals. Denominator The part of a fraction below the dividing line. For example, the 2 in 1/2 is the denominator. Equivalent fractions Fractions, having different numerators, and denominators but still have equal values, such as the two fractions, 1/2 and 3/4. Improper Fraction A fraction in which the numerator is greater than or equal to the denominator Invert To reverse the order or position of numbers. Mixed number A combination of a whole number and with a fraction or decimal. Numerator The part of a fraction above the dividing line. Joists Lengths of wood or steel that usually supports floors, ceiling or a roof. Loadbearing Carrying a significant amount of weight and/or providing necessary structural support. A loadbearing wall is typically carrying some portion of the roof weight and cannot be removed without risking structural failure or collapse. Stud The vertical framing member in frame wall construction. Force A push or a pull on a surface. Mass The quantity of matter present. Unit A definite a standard of measure. Volume The amount of space contained in a given three-dimensional space. Acute angle An angle between 0 degrees and 90 degrees. Adjacent angles Angles that have the same vertex, and one side in common. Angle The shape made by two straight lines coming together at a point. Area The surface or amount of space occupied by a two -dimensional object such as a rectangle,circle, or square. Base As it relates to triangles, the base is the line forming the bottom of the triangle. Bisect To divide into two parts that are often equal. Circle A closed curved line around a central point. A circle measures 360 degrees. Circumference The distance around the curved line that forms the circle. Cube A three-dimensional square, with the measurements in all the three dimensions being equal. Degree A unit of measurement of angles. Diagonal Line drawn from one corner of a rectangle Diameter the length of a straight line through the center of a circle Equilateral triangle A triangle that has three equal sides and three equal angles. Formula A mathematical process used to solve a problem. Isosceles triangle A triangle with at least two congruent sides
