How do you do arrays and an expanded algorithm. 23 X 17?

arrays would be....... I THINK

To perform multiplication with arrays and use an expanded algorithm for the calculation, follow these steps:

Step 1: Set up the arrays:

Create two arrays, one for each number in the multiplication problem. In this case, you have 23 and 17, so set up two arrays accordingly:

Array A: [2, 3]
Array B: [1, 7]

Since 23 has two digits (2 and 3), each digit occupies one element in Array A. Similarly, since 17 has two digits (1 and 7), each digit occupies one element in Array B.

Step 2: Expand the algorithm:

Start by multiplying the last digit of Array B (7) with each digit in Array A, one by one:

7 * 3 = 21
7 * 2 = 14

Write down the results of each multiplication:

21
+ 14

Step 3: Align the results:

Align the two numbers you obtained in Step 2, making sure the last digits are aligned vertically:

21
+ 14

Step 4: Add the aligned numbers:

Add the aligned numbers vertically:

21
+ 14
------
35

So, the product of 23 and 17 is 35.

By following these steps, you can calculate the product of two numbers using arrays and an expanded algorithm.
