Hi this is a game passed on
AceArtemis' 4 4s gameAceArtemis wrote:Basically, you have to form a number using 4 4's and any operations necessary. The first poster does the number 1, then the second poster has to do the number 2, and the next poster does the number 3, and so on.
SInce going much higher with 4s is limited i though, lets start a new one with 5's
So here i go and please show your work for easy checking
1=((5!+5)/(5*5))/5
1=((5*4*3*2*1+5)/(25))/5
1=((20*6+5)/(25))/5
1=((120+5)/(25))/5
1=(125/25)/5
1=5/5
1=1
Now your turn

2 = (((5*5)/5)+5)/5
2 = ((25/5)+5)/5
2 = (5+5)/5
2 = 10/5

You can only use 5s
6=5+(5/5)

Is a reduction. It's alllowed. In you case would be:
6=5+(5/5)
6=5+(1)
6=6. But you failed there because is with 5 fives...like
6=5+(5+5)/(5+5)
6=5+(1/1)
6=6

10=5*5-(5+5+5)
10=25-15
10=10
That was easy

Looks like that one uses seven fives.
Anyway:
17= 5!/(5+5)+√(5*5)
17=120/10+√25
17=12+5
17=17

It does that wont work ill do 16 and 18
16=(5+5+5)+(5/5)
16=15=1
16=16
18=(5!/5)-5-(5/5)
18=(120/5)-5-1
18=24-6
18=18

19=(5!/5)-5x(5/5)
19=(120/5)-5x1
19=24-5
19=19
Also, for 18, that should be plus 5/5, not minus.
18=(5!/5)-5+(5/5)
18=(120/5)-5+1
18=24-6
18=18
