Today in class we solve a number problem by using Trial and Error. We guessed a number between 1 and 10 then we multiplied the number by 3. First we tried 9x3 then we added 9+8 but it didn't work. Then we tried 7x3 and 7+8 but it didn't work. Then we tried 5x3 and 5+8 It was close but we needed 2 more numbers. Then we tried 4x3 and 4+8 which both of them equals 12 so the answer is 4.
