Some Math Teasers......

Not Prog related but I know there are a few people out there who could help me.

A friend, who knows of my love of Pure Maths, set me three questions. I did the first two in about 4 minutes but the third has me flummoxed. They are similar to the famous Four Fours test.

1) Using five fours and common mathematical symbols make the result 55.

2) Using three fours and common mathematical symbols make the result 55.

Easy peasy!!!

The one I'm stuck on is:

3) Using three fours and common mathematical symbols make the result 54.

Go for it Moonies.
