1+1+4+6+8+2+4+5+28+9+9202

First combine 4+6 to equal an easy 10 ... then combine 8+2 to make another easy 10 ... then add 28+1+1 to equal an even 30 ... so what you have left is 4+5+9+9202 ... so combine 4+5 to make 9 and add 9 (9+9) ... so now you have 18+9202 ... so 8 goes into 2 evenly, carry the 1, 1+0 is 1, then just 92, so 9210 ... so now add all of your totals, 10+10+30+9210, 10+10=20 so add 20 to 30 to get 50 and add 50 to 9210 ... so your total is 9260!
