  • As a result of every digit in binary can have 2 values, the bottom is 2 (see the instance under for clarification)

Don’t fear if it doesn’t make sense but…

  1. Beneath is an 8 digit binary quantity
  2. We calculate binary from proper to left

3. As a result of it’s a base 2 system, every digit is 2 to the facility of (n). (n) refers back to the placement of the quantity.

4. A binary quantity is just about telling us whether or not or not we’re utilizing that worth

5. The 1 worth tells us we’re utilizing that worth (represented by inexperienced checkmarks) & the 0 worth inform us we’re not utilizing that worth (represented by purple X’s).

6. The primary digit on this instance is representing that the worth 2 to the facility of 0 is ON

Let’s symbolize these 2 values in our drawing..

Let’s calculate the remainder of the values & add those which can be ON collectively…

Let’s check out our earlier instance..
