Tomorrow is Tuesday 2/22/22 (or 22/2/22, if you prefer). What a wonderfully epic Twosday!
Here’s a puzzle your family or class may enjoy…
The “All 2s” Challenge
Use only the digit 2, and try to use as few of them as you can for each calculation. You may use any math operations you know.
0 = 2 − 2
8 = 2 + 2 + 2 + 2
- Can you find a way to make 8 using fewer than four 2s?
- What other numbers can you make?
- Can you calculate all the numbers from 1–20? 1–100?
