11-2^2 = = 7
11 - (2•2) = 7
(11-1) - (2+1) = 7
(11-1) - (2•2-1) = 7
(12/2) + 1=7
(12/2) + 2-1=7
(22/11) + 1 + (2•2) = 7
11 - (22/11) ^ (22/11) = 7
(22/2) - 2^2=7
(22/2) - (22/11) ^ (22/11) = 7
11-Square root (2•2) = 7
We can think that 7 can be made with sum of two positive integers, sum of positive and negative integers, decimals, fractions, we can use sums of three numbers, just to mention a few, and rewrite each number using only 1 and 2 when possible.
0+7 - 1+8
1+6. - 2+9
2+5. - 3+10
3+4. - 4+11 etc
