In math we had to use polypad to work out. this is second time using polypad and it was fun to use and goofy around with it. How I worked out this was the first thing I did was work out that x was 12 and then I made 21 20 and 1 and then it was solved. Down below is the polypad work. first thing to do is 21 – 9 = 12 so that means that x is 12 and then make x 12 so you can see it ez to work and then make 21 20 and 1.
The 9 and the 12 and + and 20 and 1 are -.
have you used polypad before?
