5⋅4

9 answers

5⋅4 can be represented with a model by drawing 5 groups of 4 objects. Each group will have 4 objects, and there will be a total of 5 groups. This can be shown visually as 5 rows with 4 objects in each row.
how would that look like??
To represent 5⋅4 visually:

__ __ __ __ __
__ __ __ __ __
__ __ __ __ __
__ __ __ __ __
__ __ __ __ __

Each underscore represents an object. There are 5 rows, each with 4 objects. This model represents 5 groups of 4 objects, which is equivalent to 5⋅4.
how would that look like in numbers
In numbers, the representation of 5⋅4 would look like this:

4 4 4 4 4

Each number 4 represents a group of 4 objects. There are 5 groups of 4 objects, so it can be written as 5⋅4.
okay so 4+4+4+4+4 or −(−4+−4+−4+−4+−4)
The correct representation for −5⋅−4 with a model is:

−(−4+−4+−4+−4+−4)

This model represents the operation of subtracting -4, five times. Each -4 is represented as a group of negative 4 objects, and there are five groups being subtracted. This model visually represents −5⋅−4.
oh 5⋅4 is it that
Apologies for the confusion.

Yes, the correct representation for 5⋅4 with a model is:

4+4+4+4+4

This model represents the operation of adding 4, five times. Each 4 is represented as a group of 4 objects, and there are five groups being added. This model visually represents 5⋅4.
