From between the 3 and the 4 to between the 9 and the 10
That is the total weight of the dumbbell.
They both have numbers.
do you mean math equation? If you add a number to both sides of an equation you do not change it. That is called algebra
It follows from the multiplication property of equality. Dividing both sides of an equation by the same number (not by zero, of course) is the same as multiply both sides of the equation by the number's reciprocal. For example, dividing both sides of an equation by 2 is the same as multiplying both sides by 0.5.

A polygon has exactly the same number of both internal and external angles to the number of sides. Assuming external angles count, there are two times the number of sides as the total number of angles
the total mass number should be equal on both sides. conservation of mass law.

I think its a property in which both sides of an equation are equal either by adding, subtracting, multiplication, or division.

The basic principle is that (with some caveats for certain operations) you can apply the SAME operation to both sides of an equation. For instance, you can add the same number to both sides, divide both sides by the same number (watching out that you don't accidentally divide by zero), take the square root on both sides, etc.

6x - 7 = x + 38 Add '7' to both sides 6x = x + 45 Subtract 'x' from both sides 5x = 45 Divide both sides by '5' x = 9 The NUMBER !!!!!
