A Weird Calculator With Only Four Buttons
Imagine if you own a weird calculator with only 4 buttons, which perform the following 4 operations: ×3 +7 -11 ÷2.
Your challenge is increment the numbers below by pushing only a certain number of buttons on the calculator.
Let us explain with an example. 1 → 2 with 3 buttons can be solved as: +7 ÷2 ÷2.
That is: 1 +7 = 8 è 8 ÷2 = 4 è 4 ÷2 = 2
Understood? Now it’s your turn. Go!
Just in case you were wondering what the solution is without putting in all the hard work, here you go!
Cool activity, ain’t it?
