Multiplication (symbol "×") is the mathematical operation of scaling one number by another. It is one of the four basic operations in elementary arithmetic (the others being addition, subtraction and division).

Because the result of scaling by whole numbers can be thought of as consisting of some number of copies of the original, whole-number products greater than 1 can be computed by repeated addition; for example, 3 multiplied by 4 (often said as "3 times 4") can be calculated by adding 4 copies of 3 together:

There are differences amongst educationalists which number should normally be considered as the number of copies or whether multiplication should even be introduced as repeated addition.

Multiplication of rational numbers (fractions) and real numbers is defined by systematic generalization of this basic idea.

Multiplication can also be visualized as counting objects arranged in a rectangle (for whole numbers) or as finding the area of a rectangle whose sides have given lengths (for numbers generally). The area of a rectangle does not depend on which side is measured first which illustrates that the order in which numbers are multiplied together does not matter.

In general the result of multiplying two measurements gives a result of a new type depending on the measurements. For instance:

The inverse of multiplication is division: as 3 times 4 is equal to 12, so 12 divided by 3 is equal to 4.

Multiplication is generalized further to other types of numbers (such as complex numbers) and to more abstract constructs such as matrices. For these more abstract constructs the order in which the operands are multiplied very often does matter.

A. Hi: five things to remember about multiplication and division 1) multiplication is repeated addition or a number add so many times. for a example 6 time 8 6+6+6+6+6+6+6+6= 48 or 8+8+8+8+8+8 = 48 2) division is repeated subtraction or multiplication in reverse for a example 48 / 6 = 8 48-6 = 42, 42-6 = 36, 36-6= 30, 30-6= 24, 24-6= 18, 18-6= 12, 12-6 = 6 , 6-6 =0 , and if you counted the number of time you subtracted it . It was done 8 times 3) the highest single digit by single digit multiple by multiplication is 81 (because 9 * 9 = 81) Thus no single digit number time a single number will never exceed 81 4 ) Any multiplication by 5 will always end in a 5 or 0 5) If in doubt about any multiplication number… [cont.]

Does anyone have any resources for IDENTIFYING multiplication and division word problems?
Q. I don't need help teaching kids to solve multiplication and division word problems but unless they are specifically told what kind of a problem it is (multiplication or division) most can't identify on their own so they do the wrong thing. I am wondering if anyone out there has any lesson tips, resources, etc for helping students identify word/story problems. They are third graders. Thanks!

A. suppose you are choosing r objects from a set of n distinguishable objects. 1. order may be important e.g. choose 10 people out of 100 to sit at the top table of a function, where closest to host is desired there are 100 ways of choosing the first person, 99 ways of choosing the next ... 91 ways of choosing the last in general #perms = n(n-1)...(n-r+1) = n! / (n-r)! You could think of this as permuting all of the objects, but then divide by number of ways of permuting all the unchosen objects becuase you regard any arrangement of the unchosen objects as the same and dont want to double count them. 2. order may not be important, e.g. dealing a hand of cards at a game like poker. Any permutation of the chosen objects is also seen as… [cont.]
