    What do you mean exactly by "good expressions"? By "expressions", do you mean equations with variables _and_ numbers, such as (a = pi*r^2), (sin^2(x) + cos^2(x) = 1), and (e^(pi*i) + 1 = 0)?

    You can try to calculate these following expressions:

    1.

    1+2+3+4+5+6+7+......+98+99+100=?

    2.

    1+2+3+4+5+4+3+2+1=?

    3.

    111111111 x 111111111=?

    4.

    1,4,9,16,25,36,49,(?),(?)...

    5.

    1,8,27,64,125,(?),(?)...

    6.

    1^2=1

    1^3=121

    1^4=12321

    1^5=1234321

    1^6=?

    1^7=?

    7.

    12345679 x 9=111111111

    12345679 x 18=222222222

    12345679 x 27=333333333

    12345679 x 36=?

    12345679 x ?=555555555

    8.

    6 x 7=42

    66 x 67=4422

    666 x 667=444222

    6666 x 6667=44442222

    66666 x 66667=?

    ? x 666667=444444222222
