So you can’t divide a row with 5 and 121 by 5, for example. No way to turn off sound. Not the best interface. Clunky. Big numbers make the matrix distorted. ### 1/5 — Long frequent ads… *2021-09-27* I get the creator wants to monetise the product but… ### 3/5 — Not bad for row reduction. *2021-07-14* Pretty good row reduction but I am just trying to multiply matrices together and I couldn’t figure it out. An update to allow other matrix operations would be very helpful. ### 1/5 — Way too many ads... *2019-11-07* Seems like a decent enough app and could be quite useful, however, the ads start up every 10-15 secs and completely distract from the use of the app. ### 3/5 — Wonderful idea, HORRIBLE interface *2019-07-25* I like the idea of this DIY calculator, but it’s a huge pain to enter matrices and I’m not even sure how to use it to perform row operations. ## Frequently asked questions about DIY Matrix Calculator ### How does DIY Matrix Calculator help with learning?
