What are cool math games?

The goal of "2048" is to add like-numbered blocks until the numbers add up to 2,048. For example, combine two blocks with the value of four, and they combine into one block with the value of eight.\n"The Timernator" and "Arithmetic Game" are both timed games where children may practice their arithmetic. In "The Timernator," they have one minute to solve as many math problems as they can, while "Arithmetic Game" requires children to fill in the blanks of a series of equations.

What are Punnett squares?

Punnett squares can be helpful for parents and doctors who are trying to determine if a child will be born with a specific disease. If both parents are carriers for a disease like cystic fibrosis, for example, this type of diagram works to determine the probability of a child being born with that gene. It also helps to determine the probability of the child being a carrier.

What is the difference between vertical and horizontal lines?

The term "horizontal" derives from the Latin "horizontem" which means "flat." The term "vertical" derives from the Latin "vertex," which means "highest point."\nThe slope of a line refers to the change in the rise, or y-value, divided by the run, or the change in x-value. Because a horizontal line does not change in y-value with changes in x-value, its slope may be calculated as zero divided by any number. This results in a slope of zero. For vertical lines, the slope equation leads to a division by zero, which is undefined.

Where can you find free printable times table sheets?

The site Math Worksheets 4 Kids has several times tables in both color and black-and-white displays. These tables are available for numbers 1 through 16, and there are tables with answers and without them. There are also two-dimensional multiplication charts that show every combination of multiplied numbers, from 0 x 0 to 15 x 15.\nAt Math-Aids.com, users can generate multiplication tables and define the range of numbers for each chart, from 1 through 9 to 1 through 12. Users can specify the amount of the chart that is pre-filled and the amount left blank for students to fill.

What are some facts about the number 55?

Fibonacci numbers follow a integer sequence, (1, 1 ,2 ,3 ,5, 8...) by adding the previous number to the next number in sequence. Following this pattern, 55 is tenth number in the Fibonacci sequence (21+34). It is a figurate number, meaning that the same number of equally spaced dots can be arranged in the shape of a regular polygon.\nThe number 55 is also semi-prime. A prime number is divisible only by 1 and itself, while a semi-prime (also called a bi-prime) is a product of two prime numbers.\nMultiplying any odd number between 90 and 110 by 55 results in a palindrome numeral, which can be wr..

What is a 7-sided polygon called?

Polygons consist of adjoining line segments and are named based on how many sides they have. There are eight polygons that have been officially named... \ntriangle: three sides\nquadrilateral: four sides\npentagon: five sides\nhexagon: six sides\nheptagon: seven sides\noctagon: eight sides\ndecagon: ten sides\ndodecagon: twelve sides\n Other proposed names include "nonagon" for a nine-sided polygon and "undecagon" for an eleven-sided polygon.\nThe vertices of a polygon are the points where two sides meet. In an equiangular polygon, all of the angles are equal, while in an equilateral polygon,..

What is Six Sigma?

By the late 1990s, two-thirds of Fortune 500 companies were using Six Sigma. In 2005, Motorola attributed savings of $17 billion to its own use of the process. General Electric, an early adopter of Six Sigma, defines it as a process that helps a company to focus on developing and delivering products and services that are nearly flawless. The central idea, according to General Electric, is to measure the number of "defects" -- failures to deliver exactly what a customer requires -- in a process, and then systematically eliminate them until the number of defects is as close to zero as possible. ..

Does a triangle have parallel sides ?

To test if two lines are parallel, try to draw a third line connecting the two and see if it forms a right angle. When drawing a third line connecting two sides of a triangle, it is never possible to form a right angle. Shapes that have parallel lines, such as parallelograms, form right angles with this new line drawn between the sides.

How is the hypotenuse of a right triangle calculated?

A right triangle is a triangle comprising two sides, known as legs, and a hypotenuse, which is identified as the triangle's longest segment. The intersection of the two legs form a 90-degree angle, which sits opposite to the hypotenuse. The formula for finding a right triangle's hypotenuse is derived from the famous Pythagorean Theorem, which is given as a2 + b2 = c2. This special property of right triangles was discovered and named after the Greek mathematician Pythagoras. The theorem shows the correlation between the triangle's legs and its hypotenuse, where it states that the..

What is 25 as a fraction?

The value 25 percent can also be expressed as a fraction of a whole. Considering that the term "percent" is equivalent to "per 100," 25 percent can be rewritten as "25 per 100," or, in fractional form, 25/100. Reducing this fraction to lowest terms by dividing both the numerator and denominator by 25 returns a value of 1/4. Thus, 25 percent in fractional form is 1/4.
