even better The original before I can get A and B because I get Jacob. How can people there, Victor a plus B so big, shapeless beat. And with I kept very that I can't marry the one I get. So 1,000,000,000 I get And one day get my jacket. So one take at minus minus. Jake it So this is that a plus B now welcome people Who a plus TV. So multiply too. Must be prospector who were so the multi library Who with better it didn't get here it I get less. Who, Jake it now less than here The plus like any with better be didn't get TV I kept my mouth six dig Now I I kept If I get plus TV I gave it a living I get But let's do Jay get minus six Jake, it will get minus pole. Jacob. So this is that you will bless. Be nine can build a model. Better it. So the model victor a tender dunder Because I So the question I I pulled so the police padlocks competent of b j 81. So the oneness square then we'll get there was by 16 plus one. So 16 plus a one is 70. So the model a jingle do Internet seven. Now we'll compute Ben. What marked off came and if so possibly come through a man s idiot so that it's a click for I kept minus I get so the poor I kept menace I get the TV and you So you get pity I get no get minus minus, minus, minus. Here less So one plus who is TV so TV dick appear less city Gig it now end up Take the magnitude about this big in this by the vision of ice over competent of eyes td So tedious You can also say that that component off iced tea and from out of days TV certificates so tedious squared is nine lows tonight. Then you get that. I'm not getting valuable in our village. He grew Who? So this is a big job. Many judo better It minus better be. Thank you
