# Deepest Ocean

## Compare numbers using inequality signs

Take your submarine to the depths of the ocean and use inequalities to catch as many fish as possible!

### Instructions

In 'Deepest Ocean' you navigate a submarine to collect fish while comparing numbers using inequalities. Your submarine has a value, e.g. 5. Then you try to collect fish that have an inequality attached to them. e.g. <10, >3, ≥ 5. You form an inequality by putting the value of your submarine in front of the inequality that's attached to the fish.

In this case you can collect all 3 of these fish since 5<10 and 5>3 and 5≥5.

If your submarine had a value of 5 and a fish had an inequality attached to it of >8, then you CAN"T collect it, since 5>8 is not true.

There are 6 different worlds for you to play:

1. Coral Reef: using > and ≥ signs with positive whole numbers
2. Kelp Forest: using < and ≤ signs with positive whole numbers
3. Ship Wreck: using >, ≥, < and ≤ signs with positive whole numbers
4. The Abyss: using > and ≥ signs with positive / negative whole numbers
5. Volcano: using < and ≤ signs with positive / negative whole numbers
6. Atlantis: using >, ≥, < and ≤ signs with positive / negative whole numbers

The value of your submarine is not fixed, on later levels you can collect air bubbles to add to or subtract from the value of your submarine.

You need to score 600 points for Bronze, 1200 points for silver and 1800 points for gold medals.

You need to collect 6 consecutive fish to move to the next level and dive deeper.

If you make two consecutive mistakes, then you'll move back a level and float to shallower waters.
