Mathematical Puzzles : What is -LRB- -RRB- + -LRB- -RRB- + -LRB- -RRB- = 30 using 1,3,5,7,9,11,13,15 ?
If F = -LCB- -LRB- 1,2 -RRB- , -LRB- 3 , 5 -RRB- , -LRB- 4,7 -RRB- -RCB- and G = -LCB- -LRB- 1,4 -RRB- , -LRB- 3,0 -RRB- , and -LRB- 5 , 2 -RRB- -RCB- , what is F + G ? What is F \ G -LRB- using function arithmetic -RRB- ?
