Mathcad

Hello,I just started using MathCAD Prime 3.0 and stumbled upon a problem. I can't find a solution to that online.I have a question about this screenshot:Why appending a result to a variable makes the operation impossible (1st and 2nd columns)?Why showing the value of a variable makes the next operation impossible (1st and 3rd columns)?Thank you. (I hope this post is in compliance with the policy)

I’m using MathCAD Prime 9.0.0.0 and I’m running into a units error…All of the R units should be K/W, but I’m getting crazy units especially on Rmid. I attached my program as well as lecture notes that show how to do this. Look on page 44-45. Thanks,    Brent

I recently changed my laptop and I'd like to re-install Mathcad. Unfortunately I don't receive the link for the download and the same it's not in the spam.

Users who do not know their Mathcad product code can refer steps below on how to get the Product Code:   Solution: Product Code consists of 22 alphanumeric characters in length. General format of product code is xxxxxxxxxxxxxxx - xxxx – xxxx If Mathcad is purchased from PTC Web Store, product code can be found on the order confirmation E-mail as “Digital Rights” or you can locate the product code printed in the card inserted in the DVD package Customers who purchased Mathcad through the PTC web store can obtain their product code by contacting the Academic Assistance  

I’m using PTC Mathcad 10.0.0.0 (as of May 2026).  Is this the latest version?   How can I determine if there’s an update?  Where do I check?  In the software?  Somewhere on this website?   Thanks

I want to buy Mathcad Prime but I can't login to purchase. I have created an account. When I click "buy now" it opens a new tab with a login screen. I enter my information and it says "invalid username or password". I have reset it several times and after completing the reset I can see that I'm logged in because my name appears in the upper right hand corner. When I go back to the store to purchase the license, the same login screen opens up, I enter my email and newly changed password and I get the same error. What am I doing wrong here?

I have recently purchased Mathcad 15 and below is the error i am getting, even after entering login details.Your login attempt has failed. Make sure the username and password are correct. Anyone assistant will be appreciated.

I am trying to compute the equivalent annual percentage rate (APR) for a series of variable deposits with variable returns.Using the “find” function results in the error message “No solution was found...”. I tried opening up the TOL value, that didn’t help. So I tried the “minerr” function next and a different error message is displayed “Indexed assignment...”, My questions are:Which of the two errors is relevant? Can I solve equations with indexed constraints in a solve block?MP11 file is attached.Thanks for your help,

i installed mathcad prime 11 in the computer but the version that i have purchased is mathcad prime 12. I would like to request for the installer for mathcad prime 12

I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0 How would I solve this equation in mathcad: y’=(A’c*l1+A’c*l2+wcb*y’2/2)/(A’c*2+13*y’) where A’c=5.336in2, l1=26in, l2=18in, wcb=13in and y is in inches Tried using the solve block but getting errors saying variable A'c is undefined. Can solve it without units and entering the variables manually but assuming there is a better way.

 I recently started using Mathcad Prime 12 for structural engineering / Eurocode calculations and I noticed something frustrating regarding the unit system.Mathcad correctly understands that: kg/s² = N/m. However when working with line loads (common in structural engineering), Prime often displays results as “kg/s²” instead of the expected engineering SI unit: N/m or kN/m.The strange part is that under “Insert Derived Units → Force per Length” there are several imperial units available: kpi, klf, plf. but there is NO SI alternative such as N/m or kN/m.This creates a awkward workflow in SI-based calculations, especially for Eurocode and structural design where line loads are constantly used.Currently the only workaround that i found seems to be manually dividing by (kN/m) , creating display variables or manually writing the unit as text. This partly defeats the purpose of the otherwise very capable engineering unit system.Questions:Is there any hidden way to add custom SI derived units

Alguna persona que tenga acceso a MathCad que me pueda abrir un documento y enviarme los datos que tengo mi PC dañadahttps://drive.google.com/file/d/1S8_3PWGeUnYfnA4jiGYNd6JJ-22kekP5/view?usp=drivesdk

Have a good day, community. I have a problem with solving a vector-type equation. The issue is that the solution only returns the last result, ignoring the previous calculations. Could someone please help me? I’m uploading the file in Mathcad Prime V.10.
