**PASTA - **The mass of an object is the property of being more or less heavy. The mass of an object depends on its volume and the matter of which the object is constituted. The weight of an object, moreover, depends on where it is located (above the earth or moon, the South Pole or the Equator Line…): the weight measures the force with which the object is thrown.

**MATHEMATICS** - Science that studies numbers and shapes.

**GOLDEN MATERIAL** - Structured set of pieces, used in teaching the Decimal Numbering System.

**MAXIMUM COMMON DIVIDER** (Mdc) - It is the largest of the factors common to two or more given numbers. For example: 20 has as factors 2, 4, 5,10 and 20; the factors of 50 are 2, 5, 10, 25 and 50 so the Mdc (20, 50) is 10 It is calculated by breaking down the numbers into prime factors and making the product of the common factors raised to the lowest exponent.

**ARITHMETIC AVERAGE** - Quotient of dividing the sum of two or more numbers by the number of installments.

**GEOMETRIC AVERAGE - **It can be calculated by the formula _{} where x_{1},… X_{no } is the data and N is the number of data.

**MEDIANA - (Statistics)** In a sample, arranged in ascending order of its elements, is the middle number. If this sample has an even number of elements, the median will be the average of the 2 centrals. Example: the median of the sample: 1, 3, 4, **6**, 7, 11, 23 é 6.

**MEDIAN** - (trapeze) A line segment that joins the midpoints of the non-parallel sides.

**MEDIATRZ - **Perpendicular line drawn in the middle of a segment.

**MEASURE** - There are many things that are usually measured: lengths, surfaces, masses, time, angles, etc. To express the measure, we use a number and a unit of measure. Example: The road is 12 Km. At 12Km, the unit of measure is the kilometer indicated by Km.

**LOWER COMMON MULTIPLE **(mmc)** -** The smallest number divisible by the given numbers. It is formed by multiplying the common and non-common factors raised to the greatest exponent. Examples: mmc (10, 15) is 30, between 9 and 18 is 18.

**SUBWAY - **(m) main unit in length. 1m = 100 cm = 1000mm.

**THOUSAND** - 10³ = 1000. 1 followed by three zeros.

**THOUSANDTH** - If you divide a unit into 1000 equal parts, each part will be 1 *thousandth.* It is indicated 1 thousandth by: _{} or 0.001.

**MILLION** - 10^{6} = 1000000. Number 1 followed by six zeros.

**THOUSAND - **Group of 1000 units.

**MILLION** - 10³ = 1000. 1 followed by three zeros.

**MILLIMETER** - Word formed by milli (thousandth) and meter. The millimeter is the thousandth part of the meter.

**LEAST COMMON MULTIPLE** - Smallest number that is divisible by all numbers considered.

**MIN (min) - **Unit of time corresponding to the 60th part of the hour. Angular unit 60 minutes = 1 degree.

**FASHION - **It is the most popular value in a sample, that is, the one that has the most frequency. The fashion in 2, 3, 4, 2, 2, 3, 4, 3, 6, 5, 7, 2 is number 2 as it appears more often (4 times).

**MODULE** **-** See absolute value.

**MONOMY - **Expression of a product of various factors, some of which may be represented by letters.

**MOSAIC** - Design formed by one or more geometric shapes that fit together perfectly and cover a surface.

**MULTIPLICATION** **-** One of the four basic operations of arithmetic, which performs the product of two or more terms called factors. Multiplication is a repeated addition.

**MULTIPLIER** - The number by which it multiplies. In product 3 x 6 = 18, 6 is the multiplier.

**MULTIPLYING - **The number that will be multiplied by another. In product 3 x 6 = 18, 3 is the multiplicand.

**MULTIPLE** - A multiple of an integer is the product of this number by another integer. 0, 4, 8, 16… are multiples of 4.

**MULTIVOCA** - Matching one object with several others. For example, a $ 10,000 car corresponds to ten $ 1,000 bikes, at least in monetary terms.
