Got distracted with work, travel and life as usual but fear not this blog isn't dead I still collect interesting problems. Without further ado:
You have four numbers: 3,3,3,3 (four threes) using simple operations such as +, -, *, /, (addition, subtraction, devision and multiplication) produce expressions that result in numbers from 0 to 10.
For example: 3 / 3 - 3 / 3 = 0.
Note, that you must use all four 3s in each expression. Have fun!
This is very simple and relaxing puzzle that you can solve with your kids and I have tons of fun solving with my eight year old.
