Convert 101 from decimal to binary
(base 2) notation:
Power Test
Raise our base of 2 to a power
Start at 0 and increasing by 1 until it is >= 101
20 = 1
21 = 2
22 = 4
23 = 8
24 = 16
25 = 32
26 = 64
27 = 128 <--- Stop: This is greater than 101
Since 128 is greater than 101, we use 1 power less as our starting point which equals 6
Build binary notation
Work backwards from a power of 6
We start with a total sum of 0:
26 = 64
The highest coefficient less than 1 we can multiply this by to stay under 101 is 1
Multiplying this coefficient by our original value, we get: 1 * 64 = 64
Add our new value to our running total, we get:
0 + 64 = 64
This is <= 101, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 64
Our binary notation is now equal to 1
25 = 32
The highest coefficient less than 1 we can multiply this by to stay under 101 is 1
Multiplying this coefficient by our original value, we get: 1 * 32 = 32
Add our new value to our running total, we get:
64 + 32 = 96
This is <= 101, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 96
Our binary notation is now equal to 11
24 = 16
The highest coefficient less than 1 we can multiply this by to stay under 101 is 1
Multiplying this coefficient by our original value, we get: 1 * 16 = 16
Add our new value to our running total, we get:
96 + 16 = 112
This is > 101, so we assign a 0 for this digit.
Our total sum remains the same at 96
Our binary notation is now equal to 110
23 = 8
The highest coefficient less than 1 we can multiply this by to stay under 101 is 1
Multiplying this coefficient by our original value, we get: 1 * 8 = 8
Add our new value to our running total, we get:
96 + 8 = 104
This is > 101, so we assign a 0 for this digit.
Our total sum remains the same at 96
Our binary notation is now equal to 1100
22 = 4
The highest coefficient less than 1 we can multiply this by to stay under 101 is 1
Multiplying this coefficient by our original value, we get: 1 * 4 = 4
Add our new value to our running total, we get:
96 + 4 = 100
This is <= 101, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 100
Our binary notation is now equal to 11001
21 = 2
The highest coefficient less than 1 we can multiply this by to stay under 101 is 1
Multiplying this coefficient by our original value, we get: 1 * 2 = 2
Add our new value to our running total, we get:
100 + 2 = 102
This is > 101, so we assign a 0 for this digit.
Our total sum remains the same at 100
Our binary notation is now equal to 110010
20 = 1
The highest coefficient less than 1 we can multiply this by to stay under 101 is 1
Multiplying this coefficient by our original value, we get: 1 * 1 = 1
Add our new value to our running total, we get:
100 + 1 = 101
This = 101, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 101
Our binary notation is now equal to 1100101
