Final answer:
Multiplication can be represented using an array or an ordered pair problem. In both cases, the multiplication problem 4⋅5 can be solved by multiplying 4 by 5.
Step-by-step explanation:
Multiplication can be interpreted as grouping or repeated addition. In the case of 4⋅5, it means adding 4 groups of 5 together. One way to represent this as an array is by drawing 4 rows and 5 columns. Each cell in the array represents a product of 4⋅5. The total of all the cells gives us the answer to 4⋅5.
For the ordered pair problem, we can think of 4⋅5 as the x-coordinate of a point on the Cartesian plane. The y-coordinate would be 4. So the ordered pair problem would be (4, 4⋅5), which indicates that the x-coordinate is 4 and the y-coordinate is the product of 4 and 5.
In both cases, 4⋅5 can be solved by multiplying 4 by 5, because multiplication is a way of combining equal groups or repeated addition.
