England does not. Some schools in England do.
3 + 11 + 11 + 11 + 12 + 13 + 15 + 15 + 16 + 17 + 19 = 143

Expand z plus 11 times z plus 11 = (z+11)(z+11) = z2 + 22z + 121.
11 + 4x
8+11= 8+11
10 plus 1 is 11.
11 + 110 + 1100 = 1221
The 11 plus examination, which was used in England and Wales to determine admission to grammar schools, began to decline in the 1970s and 1980s. While it was officially phased out in many areas by the late 1990s, some regions continued to use variations of the test into the 2000s. Thus, there isn't a single definitive year when the 11 plus ended, as its use varied by location.
-2x + 11 + 6x = 4x + 11

9 plus 11 (20) plus 15 (35) plus 18 is equal to 53
11 + (-5) + (-12) + (-2) =11 - 5 - 12 - 2 =11 - 19 = -8
