how does multiplication and division undo each other
Operations that undo each other include: addition and subtraction multiplication and division powers and roots
Multiplication and division are related because they are the inverse of each other. 9 x 4 = 36 36/4 = 9
Inverse Operations: Divison undoes multiplication. Addition undoes subtraction. Subtraction undoes addition. Multiplication undoes division.
Your question is a little confusing. If you are asking which gets done first ... addition/subtraction or multiplication/division ... the multiplication/division is done first. In other words, in 1 + 4 / 2, you divide 4 by 2 first, then add 1. So the answer is 3.
how does multiplication and division undo each other
Division is the inverse operation to multiplication. Division by a number (other than zero) is the same as multiplication by its reciprocal.

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.
They just undo each other.
Two operations that undo each other are called inverse operations. Examples are addition and subtraction, or multiplication and division.
EQUATION
It is BIDMAS (UK) or PEMDAS (US). Not sure about other countries.BIDMAS = Brackets, Index, Division or Multiplication, Addition or Subtraction.PEMDAS = Parentheses, Exponent, Multiplication or Division, Addition or Subtraction.
For addition, subtraction, division and multiplication with other fractions
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.
