In the expression c - b = a then c is called the minuend, b is called the subtrahend and a is known as the difference (or result or answer).
Equal quantities.
no
Only like terms can be added or subtracted. 10m and 1s cannot be added; but divided, 10 m/s becomes a velocity.
Yes, that's true. Basically you can multiply and divide them; but you can't add, subtract, or compare them.
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.
Equal quantities.
Identical quantities can be added (or subtracted) from each side. Each side can also be multiplied (or divided) by any quantity.
no
Equal
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.

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

Because thats how y convert
Yes, all vectors can be added or subtracted.
Yes, the point is that if two terms (or sides of the equation) are equal, then they remain equal as long as you add or subtract the same amount, to or from both of them. It's very logical.
