There is no difference. In both cases, the place value, of any digit, is ten times the place value of the digit to its right.
Multiplying by multi-digit numbers is similar to multiplying by two-digit numbers in that both processes involve breaking down the numbers into place values and multiplying each digit by each digit in the other number. The key similarity lies in the application of the distributive property, where each digit in one number is multiplied by each digit in the other number, and then the products are added together to get the final result. This process is consistent whether you are multiplying by a two-digit number or a multi-digit number.
73 is the largest 2 digit number that is both prime and has prime numbers for both of its digits.
If you include 100 and 200, then there are 11 of them.
73 is the largest two-digit number that is prime and has prime numbers for both of its digits.
There is no difference. In both cases, the place value, of any digit, is ten times the place value of the digit to its right.
25 and 29 are both numbers between 20 and 30, 10 and 50, 1 and 100, etc. They are both 2-digit numbers. They both have a 2 in the hundred's place. They are both whole numbers.

This is only possible if one of the digits is equal to zero. There are 90 3-digit numbers with a zero in the 10's place, and 90 3-digit numbers with a zero in the 1's place - and 9 numbers that have both a zero in the 10's place and a zero in the 1's place; these would be counted double if you just add the first two. So, you get: 90 + 90 - 9 such numbers.
73 is the largest two-digit number that is prime and has prime numbers for both of its digits.
If x - y > 0, then x is greater than y.The greater positive number is the one further from zero.Which number is greater can be worked out on a digit by digit basis:To compare numbers starting with the highest place value column compare the digits, moving right a place value column until either all digits have been considered or one digit is higher than the other - the number with the higher digit is the greater number. (If a place value column is empty, its digit value is 0).
There are no pairs of 2-digit numbers with a difference of 90 if both numbers are positive or both negative. However, with one positive and one negative, there are 71 pairs.
-- both are positive numbers -- both are greater than 15 -- both are less than 1 googol -- both are even numbers -- both are written with one odd digit and one even digit -- both are powers of 2 -- both have the factors (are multiples of) 1, 2, 4, 8, and 16
Both 10 and 20 are two-digit numbers that are factors of 20.
Since both of those numbers contains four digits, there are no three-digit numbers between them.
