A multiplication sentence is a number sentence used to express multiplication. That is a type of equation the is limited to the operation of multiplication. Multiplication sentence are comprised of at least three terms: two factors and also a product, as displayed in the number below.

In a multiplication sentence, the 2nd factor is described as the multiplicand. That is the number the is multiply by the first factor, described as the multiplier. However, because multiplication exhibits the commutative property, which way that the position of either of the two components in a multiplication difficulty can it is in switched, the state multiplicand and also multiplier have the right to be ambiguous. As such, most texts just refer to both terms as determinants rather than making use of the state "multiplicand" and also "multiplier." In one of two people case, the systems to a multiplication problem is referred to as its product. The symbol "·" is likewise used to denote multiplication; it means the exact same thing together "×."
Practicing multiplication through multiplication sentences
There space a range of ways to practice multiplication using multiplication sentence such together filling in absent parts that the multiplication sentence or generating multiplication sentences based on an array.
Complete the adhering to multiplication sentences
1. 6 × 6 = ?
6 × 6 = 36
2. ? × 4 = 28
7 × 4 = 28
3. 4 × ? = 28
4 × 7 = 28
Notice the in the last 2 examples, the positions of the determinants are changed, yet the product is the same. This is due to the fact that multiplication, choose addition, exhibits the commutative property.
Another means to practice multiplication requires using arrays. Variety is an plan of objects, commonly using rows and also columns, that can really effectively represent multiplication. Having students create multiplication sentences to represent a given array can assist test and improve their understand of the principle of multiplication.
Express the variety of objects in the following selection as a multiplication sentence.

There are 3 rows and also 4 columns in the over array, therefore the array can be referred to as a "three by four array." This tells united state what we space multiplying, so every we have to do to write the multiplication sentence is determine the product:
3 × 4 = 12
Using arrays is a really common an approach for teaching multiplication since it permits for image of the multiplication problem as well as confirmation (through counting/addition) that the solution. It also demonstrates the value of multiplication end addition, in terms of efficiency, in situations where multiplication is applicable.
