Can you make 100 using exactly five 5’s… in five different ways?

1 min read

You are allowed to use any mathematical operator including exponents and factorials. Scroll down for my five ways. I had to get creative for the last one, and I must admit to spending a good part of my evening on it!

1.   5 x 5 x (5 – 5/5)

2.   5 x (5 + 5 + 5 + 5)

3.   5 x 5 x 5 – 5 x 5

4.   (5 + 5) ^ ((5+5)/5)

5.   5! – (5 + 5 + 5 + 5)

If you found any other ways, please please please submit below!
