What kind of quantities can always be added or subtracted from both sides of an equation?
Equal quantities.
Must quantities have different units before they can be added or subtracted?
no
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.
Is it true that two quantities having different dimension can be multiplied but they cannot be subtracted?
Yes, that's true. Basically you can multiply and divide them; but you can't add, subtract, or compare them.
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 kind of quantities can always be added or subtracted from both sides of an equation?
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.
Must quantities have different units before they can be added or subtracted?
no
What is a pair of scalar quantities?
A pair of scalar quantities are two physical quantities that have only a magnitude or size with no direction. Examples include mass, temperature, and speed. Scalars can be added, subtracted, multiplied, and divided like regular numbers.
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
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.

Because thats how y convert
Why vector quantities cannot be added and subtracted like scaler quantities?
Vector quantities have both magnitude and direction, so when adding or subtracting them, both the magnitudes and directions must be considered. Scalars, on the other hand, only have magnitudes and can be added or subtracted without concern for direction. This is why vector addition and subtraction involve vector algebra to handle both the magnitudes and directions appropriately.
