To test if a number is divisible by three, you add up the digits of the number. If the sum is divisible by three, then the original number is a multiple of three. If the sum is too large, you can repeat the process until you can tell whether it is a multiple of three. This is...
We show that certain sums of partition numbers are divisible by multiples of 2 and 3. For example, if $p(n)$ denotes the number of unrestricted partitions of a positive integer n (and $p(0)=1$ , $p(n)=0$ for $n), then for all nonnegative integers m ,...
In this exciting math game, your child will tackle division challenges by selecting numbers divisible by a given number. It's a fun way to practice dividing 3-digit numbers by 1-digit numbers without a remainder. This game strengthens division skills and builds confidence in math. Perfect for...
If the number's digits sum to a number that's divisible by3, then the number itself is divisible by3. If the number ends with a0or a5, then it's divisible by5. Of course, if the number is divisible twice by2, then it's divisible by4; if it's divisible by2and by3, then it'...
How many numbers between 1 and 1000 are divisible by 3? How many 4-digit multiples of 5 are there? How many 3-digit numbers can be written using the digits 0,2,2,4, and 6? How many perfect numbers are there? What is the value of the digit 3 in the number 3,725.89?
Using divisibility tests, determine which of the following numbers are divisible by 2; by 3; by 4; by 5; by 6; by 8; by 9; by 10; by 11 (say, yes or no): 1/2⋅(-1)^2÷1/2⋅(-1)^2=1/2⋅(-1)^2=1/2.
