+## Math with console
+You can also write math equation in `console` in order to know the answer to an expression.
+
+### Example:
+```js
+console.log("What's the age a decade later?");
+let age = 30;
+console.log(age + 10);
+//returns 40 in the console
+```
+
+## Booleans in console
+Another useful way developers use console is to check wether something is true or false. For instance in the example below you can check wether the age of a person being equal to 45 is true or false. 
+
+### Example:
+```js
+console.log("Are they 50 years old?");
+let age = 30;
+console.log(age === 50);
+//result: false
+```
+
 ### 📝 Tasks:
 
-* [ ] Write a program to print `Hello World` on the console. Feel free to try other things as well!
-* [ ] Write a program to print variables to the `console`. 
+*  Write a program to print `Hello World` on the console. Feel free to try other things as well!
+* Write a program to print variables to the `console`. 
   1. Declare a variable  `animal` and assign the dragon value to it.
   2. Print the `animal` variable to the `console`.
+* Write a program to print the number `45` with a math expression of your choice. (Bonus if one of the numbers is a variable!)
+
+* Write a program in the console that checks if the amounts of eggs is more than `12`.
+  1. Declare a variable `eggs` and assign a number of your choice to it
+  2. Call the `eggs` variable in the `console` and use the correct operator to see if the number assigned to `eggs` is greater that 12
+      * If the number of eggs is greater, it should print `true`, if not then it should print `false`
