Assume that the following three equations hold true:
- $C \circ I \circ D \circ A = B$
- $O \circ K \circ M \circ G = C$
- $Y \circ A \circ B \circ C = D$
Find the right hand side of the following equation:
- $S \circ W \circ A \circ G =~ ?$
Convert each letter to its corresponding numerical value.
E.g., $C \circ I \circ D \circ A = B$ is converted to $3 \circ 9 \circ 4 \circ 1 = 2$
Use mathematical operators to make above equations work out.
All the equations follow the same pattern. Just find a pattern, apply it to the last equation and find the result.
