86. Do it on a paper that's what I did but there's a way I also had in mind. 5 plus 3 is 8 and 50 plus 30 is 80 just add the 6 to the 80 and I got 86.
30 + 26 = 56
30 + 50 - 56 + 2306 = 2330
20 + 6 - 56 = -30
18/30 + 25/30 = 43/30 which cannot be reduced.
324
There are 3 ways. 30/56, 30 to 56, and 30 : 56.
5712
-45 plus 512 plus 45 plus 56 = 568
56 multiplied by 30 is 1,680.
77 plus 76 plus 69 plus 56 is equal to 278.
56 + 6612 + 2 = 6670
56 + 4 + 951546 = 951606
