One To Ten (The Old Version)

This game requires players to understand arithmetic functions and order of operations. Don't forget 'Please Excuse My Dear Aunt Sally', where the first letters form a mnemonic for the order of operations: parenthesis, exponents, multiplication and division, addition and subtraction.

Object of the Game

To create all the numbers from one to ten using the arithmetic operations and the four numbers specified by the computer.

Game Instructions

The computer selects four numbers from one to ten. You must combine these integers, using each one once, to form each of the integers from one to ten. For example, if the computer selects 1, 2, 3, and 4, you could create the following equations:

1=(2-1)*(4-3)	6=12/4+3
2=(2*1)*(4-3)	7=13-4-2
3=4-3/(2+1)	8=12/3+4
4=1+2+4-3	9=14-3-2
5=12-3-4	10=14/2+3

Enter your equations in the spaces, and click 'Submit' when you are ready for the computer to grade your response.

Game Tips

You can combine your numbers to make two or three digit numbers.
You can use parentheses, and you can even have nested parentheses.
Use '^' for an exponent. (2^3 means 2 cubed)
Each problem is solvable without parantheses or exponents.
The game refuses to do non-integer division. For example, 5/3+1/3 is an invalid equation.
