A number model is a sentence that shows how a series of numbers are related. An example of a basic number model could be 12+3=15.Continue Reading
A number model is an equation that incorporates addition, subtraction, multiplication and division, which are used singularly or together. In an equation, the symbols for these functions will be listed as, "+," "-," "*" and "/." As long as each part of the equation is related using some kind of sign, the equation is considered a number model.
In order to be a number model, an equation must show equality. For example, the equation, "8 + 1" is not a number model because it lacks the equal sign. However, "8 + 1 = 9" is a number model.
Number models can also be used to discover the perimeters and area of shapes. These types of equations may be in numeric or word form. To find the area of a square, when "a" is the length of one side, the number model would be written as: "area = a * a." Notice that in this example, there is a multiplication sign and an equal sign present.Learn more about Numbers
There are 90,000 different number combinations that can be made in a five-digit number if numbers can repeat. To determine the number of possibilities, each place digit has to be evaluated independently to see how many numbers could fit there and then all are multiplied together.Full Answer >
The prime factorization of 72 is 23x 32, or 2 x 2 x 2 x 3 x 3. The prime factorization of a number involves determining the factors of a number that are also prime numbers and multiply together to equal the original number.Full Answer >
The only common multiple of the numbers 7 and 11 from 1 to 100 is the number 77, according to the Math Warehouse calculator. A multiple is the product of a number and another whole number. A common multiple of 7 and 11 must be larger than the two numbers.Full Answer >
Prime numbers that, when multiplied, equal another number are said to be the “prime factors” of that number. For example, 2 and 7 are the prime factors of the number 14.Full Answer >
