Solve if you are Genius 4 + 2 = 4 5 + 3= 10 6 + 4= 18 Than 8 + 6= ??

First number + second number replace this by first number * (second number - 1)

4 + 2 = 4 * (2 - 1) = 4 5 + 3 = 5 * (3 - 1) = 10 6 + 4 = 6 * (4 - 1) = 18 so 8 + 6 = 8 * (6 - 1) = 40 Ans is 40

Answer is 40 4*(2-1)=4 5*(3-1)=10 6*(4-1)=18 then 8*(6-1)=40

IF 1,3,3=5 9,7,4=8 11,14,10=15 20,16,12=18 Than 3,6,7=?
