+# The Calculator
+#### Project made for freeCodeCamp "Front End Libraries Projects" module
+
+This is a project made for FreeCodeCamp in which it was required to code a calculator from scratch. Made using React.
+
+#### Screenshot
+
+This is how it looks like.

+
+#### User Stories
+
+These are the requirements for this project. They are all fullfilled.
+
+1. My calculator should contain a clickable element containing an = (equal sign) with a corresponding id="equals".
+2. My calculator should contain 10 clickable elements containing one number each from 0-9, with the following corresponding IDs: id="zero", id="one", id="two", id="three", id="four", id="five", id="six", id="seven", id="eight", and id="nine".
+3. My calculator should contain 4 clickable elements each containing one of the 4 primary mathematical operators with the following corresponding IDs: id="add", id="subtract", id="multiply", id="divide".
+4. My calculator should contain a clickable element containing a . (decimal point) symbol with a corresponding id="decimal".
+5. My calculator should contain a clickable element with an id="clear".
+6. My calculator should contain an element to display values with a corresponding id="display".
+7. At any time, pressing the clear button clears the input and output values, and returns the calculator to its initialized state; 0 should be shown in the element with the id of display.
+8. As I input numbers, I should be able to see my input in the element with the id of display.
+9. In any order, I should be able to add, subtract, multiply and divide a chain of numbers of any length, and when I hit =, the correct result should be shown in the element with the id of display.
+10. When inputting numbers, my calculator should not allow a number to begin with multiple zeros.
+11. When the decimal element is clicked, a . should append to the currently displayed value; two . in one number should not be accepted.
+12. I should be able to perform any operation (+, -, *, /) on numbers containing decimal points.
+13. If 2 or more operators are entered consecutively, the operation performed should be the last operator entered.
+14. Pressing an operator immediately following = should start a new calculation that operates on the result of the previous evaluation.
+15. My calculator should have several decimal places of precision when it comes to rounding (note that there is no exact standard, but you should be able to handle calculations like 2 / 7 with reasonable precision to at least 4 decimal places).
