What does it mean to say that multiplication and division are inverse operations?

Start with any number - say x.
Pick any other number which is not 0, say y.
Then, if you multiply x by y and then divide the result by y you will be back to x.
Thus, "multiply by y" followed by "divide by y" is equivalent to do nothing. The first undoes the second.
Also, it works in reverse in the sense that you can divide by y first and multiply by y afterwards.

What does inverse mean in arithmetic?
"opposite" operation. The inverse of subtraction is addition; the inverse operation of multiplication is division.
What does the word inverse mean in math terms?
Mathematically, an inverse is an opposite, it is something that reverses what its inverse does, for example, addition and subtraction are inverse functions, as are multiplication and division. The inverse of a fraction is obtained by exchanging numerator and denominator; the inverse of a half is two.
What can undo operations?
Inverse functions? (not sure what you mean)
What 4 kinds of mathematical values?
That depends on the values of what but if you mean arithmetical operations then they are: addition, subtraction, division and multiplication
What do multiplication and division mean in math terms?
Multiplication and division are mathematical operations. They are inverses, which means that they are opposites, so multiplying and dividing a number by the same constant yields the original number.Often multiplication is taught as taught as repeated addition- 7 multiplied by three is adding 3 sevens together. Although this works to compute positive whole numbers, it is not the mathematical definition. Mathematically, multiplication is the act of scaling numbers together.Division is the inverse of scaling numbers together. To visualize division, imagine a large object being divided into small, equal pieces.

What does that mean that the operations are inverses of pemdas?
The inverse of PEMDAS is the opposite operation order such as: S=subtraction, A=addition, D=division, M=multiplication, E=exponents, and P=parentheses.

Does division distribute over addition?
I assume you mean the 'Order of Operations' which are: 1 Brackets 2 Exponents (Powers and Roots) 3 Multiplication and Division 4 Addition and Subtraction Therefore, division will be done before addition.
What does the math term order of operations mean?
Order of operation means that you go from the left of your equation to the right always doing multiplication and division first and then addition and subtraction
What does repeated mean in math?
Division. Multiplication is repeated addition.
