Math Monkey (angrybirdstd's conception)

Math Monkeys can do addition & subtraction at first. Every 6 rounds, it adds 2 HP to towers in range including itself. Every second, it subtracts 2 HP from any bloon in range. It costs $120. Its range is that of a Super Monkey's. When the HP of a bloon is a decimal, it is rounded. Image coming!

Path 1

 * Multiplication: Now every 6 rounds, it multiplies the HP of its range by 2. $300
 * Better Multiplication: Now multiplies by 3 instead. $450
 * Squares: Now squares the HP of towers in range including itself every 6 rounds. Transforms 1 into 2. $1,000
 * Cubes: Now cubes the HP of towers in range including itself. Transforms 1 into 2. $2,000

Path 2

 * Division: Now every second, it divides bloon HP by 2. It can instantly pop bloons with 1 HP even if 1/2=0.5~1. $300
 * Better Division: Now every second, it divides blo0n HP by 2. 2/4=0.5~1, so a bloon with 2 HP that receives this will have only 1 afterwards. $450
 * Square Root: It now takes the square root of the bloon's health. Bloons with 1 HP pop. $1,000
 * Cube Root: It now takes the cube root of the bloon's health. Bloons with 1 HP pop. $2,000 Obtains MASD:
 * MASD Ability: (Mathematical Amazing Smart Duties Ability) It releases a spell that squares all of the towers onscreen. It also gets the square root of all of the bloon's health. All 1 HP bloons pop.
