Rhyme math rules

Not pretty but it rhymes. The author is happy about better and/or additional rhyme rules:

If you easily divide a by b, it doesn’t hurt when you multiply a and b**.

If you break a down into a product with cunning, so that a factor is then divisible by b, then you also divide the number a by b into pieces with cunning and trickery.

If you can divide a and b by c, you will also succeed very well with a+b.

If a and b are two completely different numbers, both of which can be divided by c without any problems, then divisible by c is also called a-b, difference, if you know that a is greater than b.

If a number ends with 0, 2, 4, 6 or 8, you can easily divide it by two. If a number ends with 0, it can handle being divided by 10. But if it has 2 of them, it can handle 100. With every additional zero in the dividend, a zero is also added to the quotient.

If 0 or 5 is called the end of the number, then divisible by 5 is known.

You can really only divide a number by 4 (25) if the last 2 digits are 00 - or divide it by 4 (25).

You can tell whether a number is divisible by 8 (125) if 3 digits at the end are 3 times 0 or if you can divide it by 8 (125).

You can only be happy about divisibility by 9 if the sum of the digits is divisible by nine.

Dividing a number by 3 is a big celebration if the sum of the digits is divisible by 3 without a remainder.
