Convert 43 from decimal to binary
(base 2) notation:
Raise our base of 2 to a power
Start at 0 and increasing by 1 until it is >= 43
20 = 1
21 = 2
22 = 4
23 = 8
24 = 16
25 = 32
26 = 64 <--- Stop: This is greater than 43
Since 64 is greater than 43, we use 1 power less as our starting point which equals 5
Work backwards from a power of 5
We start with a total sum of 0:
The highest coefficient less than 1 we can multiply this by to stay under 43 is 1
Multiplying this coefficient by our original value, we get: 1 * 32 = 32
Add our new value to our running total, we get:
0 + 32 = 32
This is <= 43, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 32
Our binary notation is now equal to 1
The highest coefficient less than 1 we can multiply this by to stay under 43 is 1
Multiplying this coefficient by our original value, we get: 1 * 16 = 16
Add our new value to our running total, we get:
32 + 16 = 48
This is > 43, so we assign a 0 for this digit.
Our total sum remains the same at 32
Our binary notation is now equal to 10
The highest coefficient less than 1 we can multiply this by to stay under 43 is 1
Multiplying this coefficient by our original value, we get: 1 * 8 = 8
Add our new value to our running total, we get:
32 + 8 = 40
This is <= 43, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 40
Our binary notation is now equal to 101
The highest coefficient less than 1 we can multiply this by to stay under 43 is 1
Multiplying this coefficient by our original value, we get: 1 * 4 = 4
Add our new value to our running total, we get:
40 + 4 = 44
This is > 43, so we assign a 0 for this digit.
Our total sum remains the same at 40
Our binary notation is now equal to 1010
The highest coefficient less than 1 we can multiply this by to stay under 43 is 1
Multiplying this coefficient by our original value, we get: 1 * 2 = 2
Add our new value to our running total, we get:
40 + 2 = 42
This is <= 43, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 42
Our binary notation is now equal to 10101
The highest coefficient less than 1 we can multiply this by to stay under 43 is 1
Multiplying this coefficient by our original value, we get: 1 * 1 = 1
Add our new value to our running total, we get:
42 + 1 = 43
This = 43, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 43
Our binary notation is now equal to 101011
We are done. 43 converted from decimal to binary notation equals 1010112.
We are done. 43 converted from decimal to binary notation equals 1010112.
