Multiplication Using Repeated Addition And Arrays

1. Using repeated addition, what is the product of 2x3?

2+2+2=6

3+3+3=6

5

The question is asking for the product of 2x3. The given answer of 2+2+2=6 is incorrect because it is using repeated addition instead of multiplication. To find the product of 2x3, we need to multiply 2 by 3, which gives us the correct answer of 6.

2. Write the addition sentence as a multiplication sentence. Example: 1+1+1=3 3x1=3

6+6+6+6+6+6=36

5x6=30

6x6=36

6x6=37

The given addition sentence "6+6+6+6+6+6=36" can be written as a multiplication sentence "6x6=36".

Explanation

The given addition sentence "6+6+6+6+6+6=36" can be written as a multiplication sentence "6x6=36".

3. Write a multiplication sentence using the array.

          ooooooo
          ooooooo
          ooooooo
          ooooooo

4x7=28

4x6=28

4x7=27

The given array has 4 rows and 7 columns, with each cell represented by an "o". To write a multiplication sentence using this array, we need to consider the number of rows and columns. Since there are 4 rows and 7 columns, the multiplication sentence would be 4 multiplied by 7, which equals 28. Therefore, the correct answer is 4x7=28.

5. Write a multiplication sentence using the array.

             $$$$$$$$$$
             $$$$$$$$$$
             $$$$$$$$$$

3x10=3

3x11=33

3x10=30

The given array has 3 rows and each row has 10 dollar signs. The multiplication sentence 3x10=30 represents the number of dollar signs in one row (10) multiplied by the number of rows (3), which gives the total number of dollar signs in the array (30).
