Operations that undo each other include:
addition and subtraction
multiplication and division
powers and roots
Inverse Operations: Divison undoes multiplication. Addition undoes subtraction. Subtraction undoes addition. Multiplication undoes division.
how does multiplication and division undo each other
If defined, they are inverse operations. However, multiplication and division is a somewhat flawed example because division by 0 is not defined. So, if you have a number x, then x*0 = 0 but 0/0 is not x: it is not defined.
Addition and subtraction are inverse operations, as one undoes the effect of the other; for example, adding a number and then subtracting the same number returns you to the original value. Similarly, multiplication and division are also inverse operations, as multiplying a number and then dividing by the same number returns you to the original value. Thus, the pairs of inverse operations are addition with subtraction and multiplication with division.
Inverse operations, or opposite operations, undo one another. Subtraction undoes addition (and vice versa), and division undoes multiplication (and vice versa).
Operations that undo each other are called inverse operations. Division is the inverse of multiplication as it undoes the multiplication. eg 3 × 7 = 21; 21 ÷ 7 = 3. Note that there is NO inverse for multiplying by 0.

Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Two operations that undo each other are called inverse operations. Examples are addition and subtraction, or multiplication and division.

To check multiplication with division, you can divide the product of the multiplication by one of the original factors. If the result equals the other factor, then your multiplication is correct. For example, if you multiply 6 by 4 to get 24, you can check by dividing 24 by 6, which gives you 4, confirming the original multiplication. This method ensures that both operations are consistent with each other.
They just undo each other.
In mathematics, an inverse operation refers to a pair of operations that reverse the effect of each other. For example, addition and subtraction are inverse operations, as subtraction undoes addition. Similarly, multiplication and division are inverses because division reverses the effect of multiplication. Using inverse operations is essential for solving equations and understanding relationships between numbers.
Both multiplication and division are important mathematical operations that build on each other. Understanding multiplication helps with calculations involving equal groups or scaling quantities, while division is necessary to share or distribute quantities equally. Both operations are essential in problem-solving and real-life applications.
