2015 Mathematics Game is here!
If you don't know, this is a fun game where we try to make the numbers from 1 to 100 using the digits 2, 0, 1, 5 and various math operations. For example, you could write
25 − 10 or
5 + 1 − 2 + 0 or
5 × (2 + 1 + 0) or
50 / 2 − 1
etc. and you'll get various numbers. The challenge is to make ALL of them from 1 to 100!
Take special note: square roots, exponents, and factorials are allowed.
This means you can do 52 + 10, √25 − 10, and 0! + 1 + 2 + 5. You can even use decimals, such as .2 to make 5 × .2 + 10.
You can submit your results to Math Forum.
Denise at Let's Play Math also accepts submissions. Her rules are a tiny bit different from Math Forum's. Check out both:
