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

## Algebric Difference in Grade formula

$$\large{ A = g_2 \;-\; g_1 }$$
Symbol English Metric
$$\large{ A }$$ = algebric difference in grade (%) $$\large{dimensionless}$$
$$\large{ g_1 }$$ = tangent grade of a slope given in % $$\large{dimensionless}$$
$$\large{ g_2 }$$ = tangent grade of a slope given in % $$\large{dimensionless}$$
