20 x 1 + 20 x 2 + 20 x 3 + 20 x 4 + 20 x 5 + 20 x 6 + 20 x 7 =
20 x 1 + 20 x 2 + 20 x 3 + 20 x 4 + 20 x 5 + 20 x 6 = ?
1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x ... x 100 = ?
20 + 20 * 2 =?
(17/20+7/20):2
20-20+20+20-20+20-20+20-20-20++20
20+20+20+20+20+20+20+20+20+20=?
Điền > < =
a) 3 x 5 ..... 3 x 6
3 x 5 ..... 3x 4
b) 3 x 5 ..... 5 x 3
4 x 6 ..... 6 x 4
c) 20 : 4 ..... 20 : 5
20 : 4 ..... 20 : 2
x + 20 = 20 x 2
