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
