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.

Why is adding subtracting and equating quantities possible only if they have the same dimension?
If they are not on the same dimension then you cannot do this. They will be different numbers and will not go together.
How do you find the dimension of a box?
Length multiplied by the height multiplied by the width Example: Box#1 Width 2cm Height4cm Length6cm 2*4*6=8*6 or 48cm cubed
Can matrices of the same dimension be multiplied?
No. The number of columns of the first matrix needs to be the same as the number of rows of the second.So, matrices can only be multiplied is their dimensions are k*l and l*m. If the matrices are of the same dimension then the number of rows are the same so that k = l, and the number of columns are the same so that l = m. And therefore both matrices are l*l square matrices.
How do you convert 10 square yards into a room size?
The only thing you can predict is that the (length) multiplied by the (width) ... if both are measured in feet ... will be 90. But you can't tell what either dimension will be.
How are the different dimension related to one another?
Space can be divided into n different dimensions. Every dimension is orthogonal to rest all the dimensions. That is the dot product of x with y is zero (y not equal to x).

How many square meter makes a meter?
you cannot compare these two quantities as they have a different dimension
What is the dimension of 27 83?
The answer will depend on (a) whet the dimensions of the two quantities are, and (b) what the missing operator between the two quantities is.
If only one dimension of a shape is doubled what is the volume multiplied by?

Is heaven invisible?
It is a different dimension; a different universe. You can only view the dimension you are presently in.
Can a 3 X 5 matrix be multiplied by a 3 X 5 matrix?
No it can't !!!Matrix property: A matrix A of dimension [nxm] can be multiplied by another B of dimension [ txs] m=t.m=t => there exist a C = A.B of dimension [nxs].Observe that given [3x5] and [3x5], 5!=3(not equal to) so you can't!
Why does efficiency have no dimension?
Efficiency is a ratio of the same quantities. Usually, output power / input power. As the numerator and denominator have the same quantities, the dimensions cancel each other out.
What is the dimension of force if density and frequency and acceleration due to gravity are the bare quantities?
Frequency and density aren't involved as 'bare quantities' in force. The bare quantities that constitute force are mass, length, and time, and the physical dimension of force is (mass) x (length)/(time)2 . The 'length' and 'time' combine to result in (length)/(time)2, and that's the 'acceleration' that you did include.
Why are the formats of the same dimension style different of GstarCAD?
The program allows dimension entities of the same dimension style to have different special parameters, that is, dimensions of the same style may have some different parameters.
Can scalar quantities be added together?
Yes, scalar quantities can be added, as long as they are the same dimension and you keep units straight. For example you cannot add cubic meters to square meters. But (especially in the imperial system) pounds and ounces, or feet and inches are added, and displayed in that fashion. Minutes and seconds is another.
Is the dimension of the frequency match the dimension of the force?
no ! dimensions of force and that of frequency are different.
What is the dimensions of the area of 196 square feet?
Any dimension where the length multiplied by the width equals 196 feet.
