If symbolically (a<b)+c is interpreted as an inequality, adding +c to it, (b+c)>(a+c), arithmetically it has to be the same to be consistent.

Why does the computational engine apply the rule of evaluating the left side first when it is an arithmetic operation? This is a standard in other CASs.

Hello
Please expand the functionality to accept a vector.

Hi, the command ARG() says Angle of a vector The arg command finds the angle of a complex number (the argument) or the angle of a vector defined by two points. arg takes v, a number or a vector defined by two points. arg(v) returns the argument of v if v is a complex number or the angle between the ...

Hello, why doesn't the distributive law apply in the arithmetic case?

(a<b)+c [enter] (b+c)>(c+a)

(9>8)-1 [enter] true-1, (1) -1 = 0
(9>8)-1 [enter] 9-1 < 8-1 , 8<7, true

Hello, I am unable to apply the distributive law in the following expression autosimplify(0) simplify(–1*(2+x+3)) => x*–1+5*–1 // It's fine, although it would look better if the numerical coefficients were placed on the left. -1*x*+5*–1 autosimplify(2) simplify(–1*(2+x+3)) => x*–1+5*–1 // would be e...

Hello,

In the Simplify ToolBox Menu, you need to add the EXPAND command, which is used a lot.

Hello

I notice that students get confused in the CAS configuration, I think it would be good to add the operation limits in some fields, for example, list the possible options

Auto simplify: 0 None, 1: Minimum 2: Maximum, 3: ...

and similar in other fields

Idea
Add a new Scripts item to the menu bar, organizing them by category, so you can quickly paste a combination of important commands.

Scripts
EXPAND/
ExpandPow: exp2pow(texpand(lnexpand(pow2exp( | ))));

Hello, this cmds script is very useful in step by step algebraic development of expressions, but difficult to remember, please add a new command or an additional parameter in an existing function

Hello

why does the distributive law not hold for complex numbers?

simplify((3+4*i)*x+(4-3*i)*y) [enter] (3+4*i)*x+(4-3*i)*y

but

simplify((3+4*j)*x+(4-3*j)*y) [enter] 4*j*x - 3*j*y + 3*x+4*y

Some menu functions that are very useful
Currently, only SELECT is available.

I like this online version because it looks like the PC version. Suggestion, the [sel] button should perform the same [Menu] functions as the PC version. I have tested on tablets and the buttons are manageable, but on a mobile it is very difficult, I think for mobiles a version with bigger buttons i...

Hello but some CAS (MAXIMA) include it within the list of set instructions, it is important to have an alias to '*' as an explicit name, I think it costs nothing to extend the functionality of this command, as well as including the complement of a set command, and creating a submenu of set commands ...

Hello xCas has set operation commands, for a future version please add a submenu 'SET' in the PC version, however the following command is very important in set theory cartesian_product( set[1], set[a,b] ) [enter] => A X B= {(1,a),(1,b)} this is to expand the functionality of cartesian_product if th...
