Today, we have an algebra riddle to kick start some more Maths revision.
'Perform the calculations required to obtain 6 as a result'
You can only use the three same numbers.
Example:
7 – (7/7) = 6
Now:
1 1 1 = 6
2 2 2 = 6
3 3 3 = 6
4 4 4 = 6
5 5 5 = 6
6 6 6 = 6
7 7 7 = 6
8 8 8 = 6
9 9 9 = 6

How did you do? Here's the answer;
(1+1+1)! = 6
2+2+2= 6
(3x3) – 3 = 6
√4 + √4 + √4 = 6
(5/5) +5 = 6
6 -6 + 6 = 6
7 – (7/7) = 6
Cube root of 8 + cube root of 8 + cube root of 8 = 6
