How does 2 4 6 1 3 equal 88 with two operational signs?

Oh, dude, it's simple math, like basic, basic math. You just take 2 + 4 = 6, then 6 x 1 = 6, and finally 6 x 3 = 18. Add those up and you get 6 + 18 = 24. So, yeah, 2 4 6 1 3 technically equals 24 with two operational signs. Easy peasy, lemon squeezy.
