+
+Variable names must be a0,a1,a2 and so on.
+
+You can use maximum 10 variables per block.
+
+Example to add 5 variables:
+
+"a0+a1+a2+a3+a4"
+
+To perform Exponential(power) calculations on operators use the following:
+
+a0**a1 
+
+To perform calculations like sqrt, log or exp use the following:
+
+sqrt(a4)
+
+log(a2)
+
+exp(a8)
