My favourite piece of technology

 

Hello everyone, a piece of technology that we all probably have in our backpack is… (music of tension) my beautiful friend <3 the calculator <3, I love how it solves mathematical problems very quickly that our teacher Victor Perez leaves us every Monday and Tuesday. There are several versions of the same device, different colors, shapes and functions. The one I use the most is the fx-350 ES PLUS scientific calculator, from Casio... it has helped me a lot at university, and it accompanies me on every adventure solving the famous derivatives, interesting functions, my beloved integrals, solving fractions and even contains my favorite number… the number pi, I need to tell you that I love mathematics, it is my favorite subject!

The other day I had a discussion with Shakira, she insists that Casio is a very bad brand.  She hates my calculator and I don't know why sho do that. I think it's a great brand that makes excellent calculators, with excellent  quality. Help me to check my calculations and pass my subjects.
