Let's divide 4 from a number and see what we get!
40 / 4 = 10
36 / 4 = 9
32 / 4 = 8
28 / 4 = 7
24 / 4 = 6
20 / 4 = 5
16 / 4 = 4
12 / 4 = 3
8/ 4 = 2
4 / 4 = 1
0 / 4 = 0
Let's raise a number to the power of 4 and see what we get!
0 ^ 4 = 0
1 ^ 4 = 1
2 ^ 4 = 16
3 ^ 4 = 81
4 ^ 4 = 256
5 ^ 4 = 625
6 ^ 4 = 1,296
7 ^ 4 = 2,401
8 ^ 4 = 4,096
9 ^ 4 = 6,561
10 ^ 4 = 10,000
Let's raise 4 to a power and see what we get!
4 ^ 0 = 1
4 ^ 1 = 4
4 ^ 2 = 16
4 ^ 3 = 64
4 ^ 4 = 256
4 ^ 5 = 1,024
4 ^ 6 = 4,096
4 ^ 7 = 16,384
4 ^ 8 = 65,536
4 ^ 9 = 262,144
4 ^ 10 = 1,048,576
Let's add 100 in Binary to a number and see what we get!
0 + 100 = 100
1 + 100 = 101
10 + 100 = 110
11 + 100 = 111
100 + 100 = 1000
101 + 100 = 1001
110 + 100 = 1010
111 + 100 = 1011
1000 + 100 = 1100
1001 + 100 = 1101
1010 + 100 = 1110
Remember, just like in a computer, there are only zeros and ones, nothing
else.
Likewise, 2*2 is also 4 because you are adding two 2's together like this: 2+2, or like this:
Or to break it down even further,
2*2 = 2+2 = 4
You can also imagine that you can get 4 if you take the cube root of 64. Since this computer cannot display balls in 3-D, you'll have to get that many blocks, and build a base 4 by 4 and stack the blocks 8 high. You'll use exactly 64 blocks to build that perfect cube.
