Mathematical Scale/Abacus/ Hanoi Tower
A number line is a pictorial representation of numbers on a straight line. It’s a reference for comparing and ordering numbers. It can be used to represent any real number that includes all integers (…-3, -2, -1, 0, 1, 2, 3,…), fractions (1/4, 1/2, 3/4…) etc.
An instrument for performing calculations by sliding counters along rods or in grooves. A slab that forms the uppermost member or division of the capital of a column
Tower of Hanoi is a mathematical puzzle where we have three rods and n disks.
The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules:
1. Only one disk can be moved at a time.
2. Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack i.e. a disk can only be moved if it is the uppermost disk on a stack.
3. No disk may be placed on top of a smaller disk.
