A.      If we are to consider that the positive (+) value is for the above the sea level and negative (-) is for below the sea level the arrangement from deepest to highest of the given is:

(a)    Snapper (-10 ft) ; (b) Redfish (-3ft) ; (c) Clam (0 ft) ; (d) Hermit Crab (2 ft)

B.      The comparison of the depth of hermit crab and redfish,

D = hermit crab – redfish = 2 – (-3) = 5 ft

The difference in the depths is equal to 5 ft. 

b). 4320 have a nice day

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
