Terrific Turtles

Congratulations, you solved the problems and played with the cutest frog ever! Since it's Friday and almost the weekend, the first mate only has three problems for you to help him with today. And he is getting out his turtles to show you. The first is his Mata Mata turtle which is a female he name Greta Greta.

Solve the problems below to see his other turtle which uses a clever camouflage technique.

Good luck!

Use symbols *, / & ^ for multiplication, division & power.
Put numbers first, then variables.
Use parentheses only when necessary.
For example: 23*x^2/(7*y)

Fantastic Frogs

Congratulations, you solved the problems and were able to feed a snake to a centipede! Today, the first mate has six easy problems for you to help him with. And to show his appreciation, he's going to let you play with his pet frogs.

The first is a Purple Harlequin Frog, discovered in 2006 during a follow-up survey of the Nassau plateau in Suriname, a country on the northeastern Atlantic coast of South America.

The second is even cooler--and you won't believe the sound it makes--but you'll have to do the problems first before you can see it.

Good luck!
