54x 3=162
54* 3= 162

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

To calculate the number of combinations for the numbers 1248, we need to consider all possible arrangements of the four digits. Since all the digits are unique, there are 4 factorial (4!) ways to arrange them. This equals 4 x 3 x 2 x 1 = 24 combinations.
54* 3= 162
the main purpose of multiplication is to multiply 1 through as many digits as you want. :)
2x2=4
The answer depends on what it is.
It depends on what is done with the digits: multiplication, insertion, addition etc.
2 and 2 0 and 0
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.
In any multiplication problem, it's never enough to know only how many digitsthe factors have. The answer always depends on what the digits are.

120 if numbers can start with 0, otherwise, 96.
Multiplication is nothing but repeated addition.We multiply whole numbers by referring to their multiplication tables and also by multiplying first the layer digit, then carrying off and then multiplying all the digits successively.
The smallest number that someone can get using the 91764 digits is 14679. The secret is to arrange the digits from the least number to their greatest number.
