# Algebric Difference in Grade

Algebric difference in grade, abbreviated as A, is the difference in grades.

## Algebric Difference in Grade formula

\(\large{ A = g_2 \;-\; g_1 }\) |

### Where:

\(\large{ A }\) = algebric difference in grade (%)

\(\large{ g_1 }\) = tangent grade of a slope given in %

\(\large{ g_2 }\) = tangent grade of a slope given in %
