This is simple subtraction to get the answer in millimetres. 20-10 gives you 10mm of a distance between both. You can simplify this answer by stating that this is also equal to 1 centimetre.
The property of equality used to solve subtraction problems is the Subtraction Property of Equality. This property states that if two expressions are equal, subtracting the same number from both sides of the equation will maintain the equality. For example, if ( a = b ), then ( a - c = b - c ). This allows us to isolate variables and solve equations effectively.
