Let's divide 2 from a number and see what we get!
20 / 2 = 10
18 / 2 = 9
16 / 2 = 8
14 / 2 = 7
12 / 2 = 6
10 / 2 = 5
8 / 2 = 4
6 / 2 = 3
4 / 2 = 2
2 / 2 = 1
0 / 2 = 0
Let's raise a number to the power of 2 and see what we get!
0 ^ 2 = 0
1 ^ 2 = 1
2 ^ 2 = 4
3 ^ 2 = 9
4 ^ 2 = 16
5 ^ 2 = 25
6 ^ 2 = 36
7 ^ 2 = 49
8 ^ 2 = 64
9 ^ 2 = 81
10 ^ 2 = 100
Let's raise 2 to a power and see what we get!
2 ^ 0 = 1
2 ^ 1 = 2
2 ^ 2 = 4
2 ^ 3 = 8
2 ^ 4 = 16
2 ^ 5 = 32
2 ^ 6 = 64
2 ^ 7 = 128
2 ^ 8 = 256
2 ^ 9 = 512
2 ^ 10 = 1,024
Let's add 10 in Binary to a number and see what we get!
0 + 10 = 10
1 + 10 = 11
10 + 10 = 100
11 + 10 = 101
100 + 10 = 110
101 + 10 = 111
110 + 10 = 1000
111 + 10 = 1001
1000 + 10 = 1010
1001 + 10 = 1011
1010 + 10 = 1100
Remember, just like in a computer, there are only zeros and ones, nothing
else.
You can also imagine that you can get 2 if you take the cube root of 8. Since this computer cannot display balls in 3-D, you'll have to get that many blocks, and build a base 2 by 2 and stack the blocks 2 high. You'll use exactly 8 blocks to build that perfect cube.
