Convert 57 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 >= 57

20 = 1

21 = 2

22 = 4

23 = 8

24 = 16

25 = 32

26 = 64 <--- Stop: This is greater than 57

Since 64 is greater than 57, we use 1 power less as our starting point which equals 5

Build binary notation

Work backwards from a power of 5

We start with a total sum of 0:

25 = 32

The highest coefficient less than 1 we can multiply this by to stay under 57 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 <= 57, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 32

Our binary notation is now equal to 1

24 = 16

The highest coefficient less than 1 we can multiply this by to stay under 57 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 <= 57, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 48

Our binary notation is now equal to 11

23 = 8

The highest coefficient less than 1 we can multiply this by to stay under 57 is 1

Multiplying this coefficient by our original value, we get: 1 * 8 = 8

Add our new value to our running total, we get:
48 + 8 = 56

This is <= 57, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 56

Our binary notation is now equal to 111

22 = 4

The highest coefficient less than 1 we can multiply this by to stay under 57 is 1

Multiplying this coefficient by our original value, we get: 1 * 4 = 4

Add our new value to our running total, we get:
56 + 4 = 60

This is > 57, so we assign a 0 for this digit.

Our total sum remains the same at 56

Our binary notation is now equal to 1110

21 = 2

The highest coefficient less than 1 we can multiply this by to stay under 57 is 1

Multiplying this coefficient by our original value, we get: 1 * 2 = 2

Add our new value to our running total, we get:
56 + 2 = 58

This is > 57, so we assign a 0 for this digit.

Our total sum remains the same at 56

Our binary notation is now equal to 11100

20 = 1

The highest coefficient less than 1 we can multiply this by to stay under 57 is 1

Multiplying this coefficient by our original value, we get: 1 * 1 = 1

Add our new value to our running total, we get:
56 + 1 = 57

This = 57, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 57

Our binary notation is now equal to 111001

Final Answer

We are done. 57 converted from decimal to binary notation equals 1110012.


What is the Answer?

We are done. 57 converted from decimal to binary notation equals 1110012.
