Remember the commutative property of multiplication: 4 x 2 is the same as 2 x 4. The number of digits in a product can not exceed the number of digits in the multiplier and multiplicand: the product of 23 X 234 is five digits or less.
744 digits.
No. They are not at all the same thing. A multiplication array is something that you usually use when you're learning multiplication. For example: there are 5 rows of 7. Its a picture that shows something like that. On the other hand, a commutative property is 2 numbers that you can multiply very easily in your head. The numbers are between 0 and 9. If they are double digits, they're not commutative property.

The communative property is that if you switch digits around in an equation that is multiplication or addition, you get the same outcome anyway. Examples: 6x3=18 3x6=18 4+28=32 28+4=32

The decimal system has ten digits (0 through 9)
There are the digits 1 through 9 for the first digit. Then, we have 0 through 9 for the second digit - excluding the first digit. For the third digit, we have 0 through 9 excluding the two previous digits
Almost got me on this one. 20 numbers but 29 digits
249 + 318 = 567

The sum of the digits of a number often reveals patterns, such as divisibility rules. For example, a number is divisible by 3 if the sum of its digits is divisible by 3. Additionally, the sum can provide insights into the number's properties, such as whether it is odd or even. Observing the sum of digits can also help identify sequences or trends in larger datasets.
The structure of the card number varies by system. For example, American Express card numbers start with 37; Carte Blanche and Diners Club with 38.American Express - Digits three and four are type and currency, digits five through 11 are the account number, digits 12 through 14 are the card number within the account and digit 15 is a check digit.Visa - Digits two through six are the bank number, digits seven through 12 or seven through 15 are the account number and digit 13 or 16 is a check digit.MasterCard - Digits two and three, two through four, two through five or two through six are the bank number (depending on whether digit two is a 1, 2, 3 or other). The digits after the bank number up through digit 15 are the account number, and digit 16 is a check digit.
