Digit Think of a number consisting of two digits. As an example, let us choose the number shown in the simulation window, that is the number 35. Add the two digits (3 and 5) of this number, that is 3 + 5 = 8. Subract the last solution (8) from the first number (35), that is 35 - 8 = 27. Find the answer (27) i the number form to the left in the simulation window and notice the symbol (figure) to the right of this number (27). Then click on the blue disc in the simulation window. What do you observe? Then select another number consisting of two digits, that is select a number in the interval [10,99], and then repeat the procedure described above. Try to explain what you are observing! If you have a problem to explain, then look at the solution. |
