EQUATION
Division is the inverse operation to multiplication. Division by a number (other than zero) is the same as multiplication by its reciprocal.
The inverse operation of addition is subtraction. The inverse multiplication by a number other than 0 is division. Multiplication by 0 does not have an inverse operation.
Operations that undo each other include: addition and subtraction multiplication and division powers and roots
how does multiplication and division undo each other
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.
Of the five common operations addition, subtraction, multiplication, division, and power, both addition and multiplication are commutative, as well as associative. The other operations are neither.
Depending on what you wish to do, it is multiplication or division. But not addition or subtraction, nor other arithmetical operations.
If an operation calls for multiplication we multiply; if it calls for any other operation, we perform the other operation!
It depends on whether the operation is addition, subtraction, multiplication, division, exponentiation or some other binary operation. One of the simplest answers is 20+20 and 10+30
Division is the inverse operation of multiplication. If a x b = c, then c / b = a. Also, division by a number can be defined as the multiplication by the number's reciprocal. Thus, a / b is the same as a x (1/b).
Multiplication and division are related because they are the inverse of each other. 9 x 4 = 36 36/4 = 9
They just undo each other.
