Why can quantities with different units never be added or subtracted bwhy can quantities with different units never be added or subtracted but can be multiplied or diviut can be multiplied or divided?
Only like terms can be added or subtracted. 10m and 1s cannot be added; but divided, 10 m/s becomes a velocity.
Why can quantities with different units never be added or subtracted but can be multiplied or divided?
Because thats how y convert
What kind of quantities can always be added or subtracted from both sides of an equation?
Equal quantities.
Can large quantities can always be added or subtracted from both sides of an equation?
The size of the quantities involved doesn't matter. As long as you add or subtract (or divide or multiply) the same number to or from both sides of the equation, then the two sides remain equal.
Why can't fractions with two different denominators be added or subtracted?
Because God made it so O.o

Equal quantities.
What quantities can always be added or subtracted from both sides of an equation?
Identical quantities can be added (or subtracted) from each side. Each side can also be multiplied (or divided) by any quantity.
Which quantities can always be added or subtracted from both sides of an equation?
Equal
What quantities can always be added or subtracted from both sides of an equationacted from both sides of an equation?
Quantities that are equal can be added or subtracted from both sides of an equasion. For example: x + 2 = 36 subtract both sides by 2 x = 34
Is volt a vector quantity?
no volt is not a vector quantity because it has no direction and it can be added or subtracted as scalar quantities. volt in electrostatics is analogous to vertical height in mechanics . vertical height have a value for every place but no direction and height can be added or subtracted as scalar
Why vector quantities cannot be added and subtracted like scalar quantities?
Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.
Can any two vectors be added or subtracted?
Yes, all vectors can be added or subtracted.
Can large quantities can always be added or subtracted from both sides of an equation?
The size of the quantities involved doesn't matter. As long as you add or subtract (or divide or multiply) the same number to or from both sides of the equation, then the two sides remain equal.

What is name the units that are being added or subtracted in a fraction?
The numerator is whats being subtracted or added when you are subtracting or adding a fraction
