Any number can be represented as a sum of powers of 2 (binary decomposition), where each power of 2 is either included or excluded. For example, 45 can be decomposed as 32 + 8 + 4 + 1, which are all powers of 2 (2^5, 2^3, 2^2, 2^0). This method allows any number to be constructed by selecting which powers of 2 to include, providing a systematic way to represent numbers using only doubling operations.

[music] [music] [music] [music] >> 6 * 10 makes 60. Count with us, the answer is 60.
6 * [music] 12 is 70, [singing] yeah.
6 * 11 is 66. [singing] 6 6 * 2, here we go. Count with us, watch us grow.
>> [music] >> The answer is 12. 6 * 3, let's calculate.
The answer is 18, it's really great. 6 [music] * 4 [singing] = 24.
6 [music] * [singing] 5 = 30.
6 * 6 = 36.
We read the numbers [music] to calculate. It's 6 * 8, watch us integrate. The result [music] is 48.
6 * 7 = 42.
6 * 9, let's calculate.
The answer is 54.
4 + 5 + 5 = 14 4 + 4 + 4 = 12 7 + 3 + 3 = 13 7 + 2 + 2 = 11 6 + 3 + 3 = 12 9 + 7 + 7 = 23 9 + 8 + 8 = 25 3 + 5 + 5 = 13 Read the numbers and calculate.
3 + [music] 4 + 4 = 11 3 + 2 + 2 = 7 >> [music] [music] [music] [music] [music] [music] >> a a a chew a a a chew a a a chew a a a chew a a a chew a a a chew a a a chew a a a chew a a a chew a a a chew a a a chew >> Hello cubes.
