Great Wall

The Great Wall (named after the and also as an upgrade for the Berlin Wall) is equal to E100#^^#^^#>#^^#^^#>#^^#^^#>...>#^^#^^#>#^^#^^#100 (10,000,000,000 #^^#^^#'s) in Extended Cascading-E Notation. The term was coined by Sbiis Saibian.
Unlike the Berlin Wall, due to order of operations, it should be evaluated as E100#^^(#^^#>#^^(#^^#>#^^(#^^#>...>#^^(#^^#>#^^(#^^#>#^^(#^^#>#^^#^^#))))))100 with 10,000,000,000 ^^#'s, making this number become much larger, and can be approximated as E100#^^^#10,000,000,000.
