You calculate binary by reading right-to-left example below (so for example the word: Binary would be read as yraniB got it? Hope so. ←>→
remember that 0's means 🟩 and 1's are 🟥 (aka on or off)
Because it’s a base 2 system, each digit is 2 to the power of (n). (n) refers to the placement of the number.
❌ | ✔️ | ❌ | ✔️ | ✔️ | ❌ | ❌ | ✔️ |
---|---|---|---|---|---|---|---|
0 | 1 | 0 | 1 | 1 | 0 | 0 | 1 |
↓ | ↓ | ↓ | ↓ | ↓ | ↓ | ↓ | ↓ |
2⁷th | 2⁶th | 2⁵th | 2⁴th | 2³th | 2²th | 2¹th | 2⁰th |
0 | 1 |

- The 1st row represents ON's and OFF's
-
- The 2st row represents the example used in the picture
-
- The 4th row represents the power of each number in the 1st row equation structure is as follows:
(char x 2(n))
char being the number in the 2nd row of a power of 2 so starting with the far right one (which in binary is actually the starting point "remember"!?) so the number 1 multiplied by 2 to the power of 0 is equal to 1 The 1 value tells us we are using that value (represented by the green✔️'s) & the 0 value tell us we are not using that value (represented by red ❌'s).
