Multi-Level Parenthesis

How to write a simple expression with multi-level parenthesis in Math Cad Prime:

A={[(2+3)*5+(4+1)*8]*7+(2+4)}*6

This is very easy in Math Cad 15, but in Math Cad Prime when I open a parenthesis the program automatically inserts closing parenthesis not in the location I need; very frustrating.

I have found that one method of adding parentheses is to highlight the portion of the equation or expression you want to separate with the parentheses, and then add a parentheses at the beginning or end:

Good luck!

Not necessary! If you highlight the subexpression 2+3 and then type *, Prime will add the necessary pair of parentheses automatically.

You should only use ( and ) for parentheses in equations.  If you type [ you are creating a vector.

If Prime detects it is necessary, it will automatically display some brackets in an expression as [  and ]. There is no user control on that.

 

Success!

You may type three opening parenthesis  to start with and then type in the numbers at the position needed.

 

But you can also type in the whole expression without having to type a single parenthesis if you take advantage of the space key to highlight subexpressions:

Type in as follows (sp means pressing the space key) :

 

2 + 3 sp sp * 5 + 4 + 1 sp sp * 8 sp sp sp * 7 + 2 + 4 sp sp sp * 6 =

 

In case you insist on the unnecessary pair of parentheses around (2+4) you may type it as follows:

 

2 + 3 sp sp * 5 + 4 + 1 sp sp * 8 sp sp sp * 7 + 2 + 4 sp sp ) sp sp * 6 =
