October Question of the Month for Algebra One

Use the number 4 four times with any operations and symbols to find the numbers 0 through 9:

  For example:   0=4+4-4-4
                        1=(4x4)/(4x4)
 2=
 6=
 3=
 7=
 4=
 8=
 5=
 9=

There are many possible solutions, such as:

    2=(4x4)/(4+4)

    3=((4x4)-4)/4

    4=(4-4)/4+4

    5=4(4-4)+4

    6=(4+4)/4+4

    7=4+4-(4/4)

    8=(4x4)-4-4

    9=(4/4)+4+4
