Coefficient result in square parentheses

Coefficient result in square parentheses

Hello.

 

Why is the calculated value given in square parentheses? Is there any specific reason for it?

As I guessed! 😉

 

When you defined C.17 and all subsequent variables you uses square brackets where you rather should have used parentheses! So you created all these variables as 1x1 matrices.

Note the difference:

Thank you. But what is the reason for square parentheses?

Why do you think that we can tell you that just from the pic you posted?

We don't see if you use vector indices or literal indices, we don't see how you defined A and C, ...

Post your sheet and chances are that you get an explanation why your result is a 1x1 matrix.

There is no vectors and no matrices in my calculations. Simple formulas as I posted the picture of.

 

Next time, I will  be more precise. Sorry.

No, thats not true for sure!

My best guess is that you used square brackets instead of parentheses when you defined one or more of your variables.

Typing square brackets automatically creates a vector/matrix.

The last result is a 1x1 matrix because [b+c] is a 1x1 matrix.

 

Give it a try and evaluate each of the three involved variables (A.1, C.17,C.30) and you will see that at least one of them is a 1x1 matrix.
