explain how you can break numbers apart to find the product of 7 X 13
You can use the product from 4x7 to find the product of 8x7 by doubling the answer to 4x7. The product of 4x7 is 28 and the product of 8x7 is 56 (28 doubled is also 56).
1. find the product of the first two 2. multiply that product with the third number
find the product of 0.056 and o.73
You might use the array to store the results, since a number may be made up of several prime factors. As soon as you find a prime factor, save the result to the array, and continue looking for additional factors. If you want all factors, not just prime factors, the principle is the same; you can store the results of your calculations to an array.
The number of elements in a 5 x 46 array = 5*46.
The number of elements (cells) in a 5 x 46 array = 5*46.

Basically, &array[i]; That is, the memory location for an array object with index i. Or, you can do: (array + i);
You can do 4 rows and 13 columns and you get 52. product = sizeof (char [4][13]); of course it is just a joke, in actual code you write product = 4*13;
by using index position we can find the particular element in array.

printf ("3*19 is %d\n", sizeof (char [19][3])); Warning: never do this in an actual program!
To find the size of an array in PHP you can either use the count() function or the sizeof() function as they will produce the same result. <?php $array = array(1, 2, 3, 4, 5, 6, 7); echo count($array); // outputs 7 echo sizeof($array); // outputs 7 ?>
array.length will return the number of elements in array.
