Let's divide 7 from a number and see what we get!
70 / 7 = 10
63 / 7 = 9
56 / 7 = 8
49 / 7 = 7
42 / 7 = 6
35 / 7 = 5
28 / 7 = 4
21 / 7 = 3
14 / 7 = 2
7 / 7 = 1
0 / 7 = 0
Let's raise a number to the power of 7 and see what we get!
0 ^ 7 = 0
1 ^ 7 = 1
2 ^ 7 = 128
3 ^ 7 = 2,187
4 ^ 7 = 16,384
5 ^ 7 = 78,125
6 ^ 7 = 279,936
7 ^ 7 = 823,543
8 ^ 7 = 2,097,152
9 ^ 7 = 4,782,969
10 ^ 7 = 10,000,000
Let's raise 7 to a power and see what we get!
7 ^ 0 = 1
7 ^ 1 = 7
7 ^ 2 = 49
7 ^ 3 = 343
7 ^ 4 = 2,401
7 ^ 5 = 16,807
7 ^ 6 = 117,649
7 ^ 7 = 823,543
7 ^ 8 = 5,764,801
7 ^ 9 = 40,353,607
7 ^ 10 = 282,475,249
Let's add 111 in Binary to a number and see what we get!
0 + 111 = 111
1 + 111 = 1000
10 + 111 = 1001
11 + 111 = 1010
100 + 111 = 1011
101 + 111 = 1100
110 + 111 = 1101
111 + 111 = 1110
1000 + 111 = 1111
1001 + 111 = 10000
1010 + 111 = 10001
Remember, just like in a computer, there are only zeros and ones, nothing
else.
You can also imagine that you can get 7 if you take the cube root of 343. Since this computer cannot display balls in 3-D, you'll have to get that many blocks, and build a base 7 by 7 and stack the blocks 7 high. You'll use exactly 343 blocks to build that perfect cube.
