Divisibility Rules 2 if it is even 3 if the sum of digits is a multiple of 3 4 if the last two digits is a multiple of 4 6 if it is divisible by 2 and 3 8 if the last three digits is multiple of 8
How do i multiple double digits for example 73×28
The sum of the number of digits in all the numbers between 31 and 400 inclusive is 1041.
numbers that do not end in 0, 2, 4, 5, 6 or 8; numbers whose digits do not total 3 or a multiple of 3
Counting all integers from 1 to 238 inclusive, there are 606 digits between these two numbers.

Yes If a numbers last two digits (assuming that it has at least two) is a multiple of 4, the whole number is also a multiple of 4. If the last two digits are 00 (assuming in this case it has at least three digits), the number is also a multiple of 4. For example, 100 and 200 are multiples of 4.
