If you have to stick with positive whole numbers,
then there are only two:
1 x 25
and
5 x 5
1234780979
15x2x10
Oh, what a happy little question! Let's explore the wonderful world of multiplication with the number 36. We can find combinations like 1 x 36, 2 x 18, 3 x 12, 4 x 9, and 6 x 6. Each combination is like a unique brushstroke on the canvas of mathematics, creating a beautiful and colorful pattern of possibilities. Just remember, there's no mistakes in math, only happy accidents!
To ensure that all possible multiplication combinations for a number are found, systematically list all pairs of factors that multiply to that number. For any integer ( n ), check pairs starting from 1 up to ( \sqrt{n} ), as any factor larger than ( \sqrt{n} ) would have a corresponding smaller factor. Additionally, confirm that each pair is unique and ordered to avoid duplicates. This method guarantees that all combinations are accounted for efficiently.
To find pairs of numbers that multiply to equal 75, you can consider several combinations. For example, 1 x 75, 3 x 25, and 5 x 15 are all valid pairs. Additionally, 7.5 x 10 also equals 75. Each pair provides a different way to express the multiplication that results in 75.

Their is 25 combinations
52=25
There are 480,700 combinations and I am not going to even try to list them!
5x5=25.
Associative works for addition and multiplication. Commutative works for addition and multiplication Distributive works for addition, multiplication and subtraction as well as some combinations of them, but not for division. Nothing works for division.
