Why do I need to learn Binary?

Answer 1

You don't.

Answer 2

you dont really need it if you are just beginning to program

and its not hard to learn how to count in binary, im actualy going to explain half of it now

we normaly use decimal system, that is numbers 0-9. When you count up, when you reach 9, you add 1 to the digit to the left of the 9, and change 9 to 0. Counting up: 8, 9, 10(!) , 11 ... 17, 18, 19, 20(!).
Binary is the same, but instead of numbers from 0 to 9, you have 0 to 1.
So counting up from 1, you will have to do the same thing as when you count up from 9, that is add 1 to the digit on the left and change the current digit to 0
So, counting from 0 you have: 0, 1, 10, 11, 100, 101, 110, 111, 1000
