Game: Count To 100 Using 4 Digits

Ok this should be interesting: (normally the numbers used would be the current year, but that will allow people to cheat )

Using the digits 2, 6, 7, 9 and the operations +, -, *, /, sqrt (square root), ^ (raise to a power of), and ! (factorial), and the along with grouping symbols, to write expressions for the counting numbers 1 through 100.

All four digits must be used in the expression.

Complete Rules

• Only the four digits (2, 6, 7, 9) are allowed.
  
• All four digits must be used in each expression.
  
• Multi-digit numbers such as 26, 267, or .79 MAY be used.
  
• You can only use each digit once.

Below are examples of valid answers:

7+6-9-2= 2

This doesn't have to be in order as such, but try to... so let's start with trying to work out how to get the value 1

[Dave]

1:

(sqrt(9)+6-7)/2= 1

[Waffle Factor]

(9-6)!-7+2 = 1

edit: oh grrr hold on ill do 2

[Dave]

2:

7+6-9-2=2

[Waffle Factor]

lol brain freeze gah

[Dave]

3 seems to be a bit of a difficult one

[Waffle Factor]

Got it!

6-(27/9)=3

[Dave]

4:

7+9-(2*6)=4

[Milosevic]

6-7+2(sqrt(9)) edit to late

[Dave]

5:

(sqrt(9)*2)-7+6=5

[Milosevic]

6:
9-7*6/2

[Dave]

6:

sqrt(7+2)+9-6=

(9-7)*(6/2)

Brackets make a difference

i am so confused, i am going to bed lol

[Milosevic]

(6squared +9 + 2 squared) /7 is that allowed

[Waffle Factor]

lol i replaced 2 with 1 got a problem?

[Milosevic]

you didn't use 2 and no ones
it is 2 ^0 + 9^0 +7^0 + 6

No squaring allowed Only operations allowed are the ones specified above, I have 8 btw, but not 7

[Waffle Factor]

Theres no zeroes to be used lol. We are still on seven right?

[Waffle Factor]

7:

7^(9-6-2)=7

[Waffle Factor]

8:

6!/9-72 = 8

ownage?

ownage?

Dam you ¬_¬ Nice.

[Dave]

9:

sqrt(9^2)/(7-6)=9

[Dave]

10:

sqrt(9^2)+sqrt(7-6)=10

[Dave]

11:

(sqrt(9)+(2*7))-6=11

[Dave]

12:

sqrt(7+9)+6+2=12

[Dave]

13:

sqrt(9)+(6/2)+7=13

[Dave]

14:

sqrt(9)+6-2+7=14


Have Fun

[Waffle Factor]

Damn and I felt nerdy doing 2 in a row

[Zat]

15:

2^(9-6)+7=15
