Calculator w/ React, Styled Components, Flexbox, Grid

Hello, bluerhythmz! 👋 Well done on this challenge! Here's a few things I'd suggest you to take a look at:

• I found a bug when I click for number, then any of operator like / * + - and then if i want to click DEL whole page disappear.
• Your output numbers are overflowing when they're longer. Keep up the good work! 💪

1. you cannot add 2.5 + .5 it results in 7.5
2. you might want to add keyboard inputs
3. also to make the = button do the last operand like 2+2 =4 and it you hit equals again it would result in 6, 8 , 10, 12
4. good thing to use a real calculator and check its functionality against yours
