Daily UI_Day #004_Calculator

Hi everyone!
Today I am happy to share with you my Calculator!
I've seen that there are a lot of amazing examples, but I haven't seen anything thought for a very young user who might be used to have an Abacus at school, therefore I tried to inspire my calculator to this instrument, using a lot of colors and a very simple ui.
I really hope you like it!
Please, leave a comment and tell me what you think! :)
