Maths Game - "Reversity"

This is a maths game that I strongly recommend to anyone who like to keep their brain active.

You will find it wonderful and importantly, it is free and requires only a piece of paper and a pencil to go with it.

This activity is not new. I have seen many with deviation.

Here I will share with you the concept.

CONCEPT: The target ( a list of number from 1 to 10, or similar list) is to be produced using a set of pre-defined numbers, or a certain number only. Any mathematical operation can be utilised to achieve the target.

Example:

To produce a list of number from 0 to 10 using ALL the numbers 1, 2, 3 and 4, with any of the mathematics operators, + , -, /, x, ) ( and exponential.

Here it goes...

0 = 4 - 3 - ( 2 - 1 )
1 = (4 - 2 )/ (3 - 1 )
2 = (4 + 2¹) / 3
3 = 4¹ + 2 -3
4 = 4 x 2 - 3 - 1
5 = 4 x 2 - 3¹
6 = 4 + 2 / 1³
7 = 4 + 3 / 1²
8 = 4 x 2 / 1³
9 = 4 x 2 + 1³
10 = 4 x 2 + 3 - 1

This is a simple maths game, but it involves the application of the basic principle of mathematics to achieve the targeted number for a given set of constraints.

"Reversity" - a reversal of the mathematical procedure.

Another tougher Reversity game is to have only the number 4 used.

Any deviation can be created to generate different levels of difficulties. Explore it!

Keep your mind in reverse gear ....... ! s r e e h C (reversed)

Number Game To Make Maths Fun

Purely studying maths as it is may tied up students mentally, not to mention the staff teaching it. How to make it interesting?

You can play games with maths. With a bit of creativity, you can create lots of fun.

I just encountered one word game initiated by a nice member at the social site BlogCatalog .

The game started with a word (has to be more than 5 letters). The next member has to continue with another word but has to start it using the last letter of the previous word. Sort of fun going especially when you see the people whacking at the comment space to participate.

Improvise this concept to maths :

Maths Game

Make use of any 3 different maths operators to generate the number 18.

Rule of the game: The last maths operator has to be the first for the next person to continue, and no numbers in the operation are to be the same.

Start: 18 ==> 40 / 2 - 5 + 3 ==> .......

Happy thinking :D
